Northern Ireland gas industry

Energy Technology Data Exchange (ETDEWEB)

Anderson, R S [Belfast City Council Gas Dept.; Asquith, R S; Brown, J M; McKay, G

1977-07-01

Throughout Northern Ireland the production of town gas is derived from hydrocarbon feedstocks. In the larger undertakings in Northern Ireland the feedstock is light distillate; a light petroleum feedstock which is a crude gasoline comprised mainly of pentanes, reformed in catalytic plants. The remaining gas undertakings produce a liquefied petroleum gas (LPG)/air mixture using a mixture of either butane or propane and air. The individual gas units and the type of reforming feedstock are shown. A review of the oil-dependence of town gas and electricity production in Northern Ireland has been considered and is mainly responsible for the high fuel prices experienced in the community. A detailed description of the reforming process has been described, and considerable efforts have been made to optimize the process. In spite of substantial economic savings being made on the processing unit, the gas industry is very susceptible to the changes in oil prices which have escalated rapidly in recent years. The difference in gas prices between the United Kingdom and Northern Ireland indicates that North Sea gas would offer major economic benefits to the gas industry in Northern Ireland, which is operating at a substantial loss at the moment. The industrial concerns, which are dependent on gas and therefore paying high fuel costs, suffer in competition with outside companies. The injection of a moderately cheap natural gas supply to the community may encourage industrial expansion and provide work in a high unemployment area. Although substantial costs must be incurred in distribution pipelines and burner conversions if Northern Ireland changes to natural gas, there appears to be a strong case to introduce North Sea gas in the near future.

Pt-modified carbon nanotube networked layers for enhanced gas microsensors

International Nuclear Information System (INIS)

Penza, M.; Rossi, R.; Alvisi, M.; Suriano, D.; Serra, E.

2011-01-01

Carbon nanotubes (CNTs) networked films have been grown by chemical vapor deposition (CVD) technology onto miniaturized low-cost alumina substrates, coated by nanosized Co-catalyst for growing CNTs, to perform chemical detection of toxic gasses (NO 2 and NH 3 ), greenhouse gasses (CO 2 and CH 4 ) and domestic safety gasses (CO and C 2 H 5 OH) at an operating sensor temperature of 120 °C. The morphology and structure of the CNTs networks have been characterized by scanning electron microscopy (SEM). A dense network of bundles of multiple tubes consisting of multi-walled carbon nanostructures appears with a maximum length of 1–5 μm and single-tube diameter varying in the range of 5–40 nm. Surface modifications of the CNTs networks with sputtered Platinum (Pt) nanoclusters, at tuned loading of 8, 15 and 30 nm, provide higher sensitivity for significantly enhanced gas detection compared to un-decorated CNTs. This could be caused by a spillover of the targeted gas molecules onto Pt-catalyst surface with a chemical gating into CNTs layers. The measured electrical conductance of the functionalized CNTs upon exposures of a given oxidizing and reducing gas is modulated by a charge transfer model with p-type semiconducting characteristics. The effect of activated carbons as chemical filters to reduce the influence of the domestic interfering alcohols on CO gas detection has been studied. Functionalized CNT gas sensors exhibited better performances compared to unmodified CNTs, making them highly promising candidates for functional applications of gas control and alarms.

2015-01-01

The CO sensing properties of a micro thermoelectric gas sensor (micro-TGS) with a double AuPtPd/SnO2 and Pt/α-Al2O3 catalyst were investigated. While several nanometer sized Pt and Pd particles were uniformly dispersed on SnO2, the Au particles were aggregated as particles measuring >10 nm in diameter. In situ diffuse reflectance Fourier transform Infrared spectroscopy (DRIFT) analysis of the catalyst showed a CO adsorption peak on Pt and Pd, but no clear peak corresponding to the interaction between CO and Au was detected. Up to 200 °C, CO combustion was more temperature dependent than that of H2, while H2 combustion was activated by repeated exposure to H2 gas during the periodic gas test. Selective CO sensing of the micro-TGS against H2 was attempted using a double catalyst structure with 0.3–30 wt% Pt/α-Al2O3 as a counterpart combustion catalyst. The sensor output of the micro-TGS decreased with increasing Pt content in the Pt/α-Al2O3 catalyst, by cancelling out the combustion heat from the AuPtPd/SnO2 catalyst. In addition, the AuPtPd/SnO2 and 0.3 wt% Pt/α-Al2O3 double catalyst sensor showed good and selective CO detection. We therefore demonstrated that our micro-TGS with double catalyst structure is useful for controlling the gas selectivity of CO against H2. PMID:26694397

World electricity and gas industries

Electric and gas utilities are central middlemen in the energy business. Worldwide, more than 50% of all primary energy is transformed by utilities and delivered to final consumers through utility wires and pipes. The structure and behavior of the electricity and gas industries and the role and behavior of utilities are therefore important to all other energy industry players. The electricity and gas industries are special. Unlike oil, coal, or wood, electricity and gas are transported from producers to consumers mostly via fixed grids. This means that supplies are generally tied to specific markets and, unlike an oil tanker on the high seas, cannot be easily diverted elsewhere. These grids are natural monopolies inasmuch as having more than one wire or pipe along a given route is generally unnecessary duplicative. In addition, both supply and grid investments are generally large and lumpy. Industrial organization theory suggests that the coordination of industries can be achieved either through hierarchies or through markets. Hierarchies are generally preferred when the transaction costs of coordinating through markets is too high. These two elements of electricity and gas industry structure are the means of hierarchical coordination. This paper discusses the possibilities for changing the structure of utilities to one which has greater reliance on markets

An overview of the Bulgarian natural gas industry is presented. The starting point was the discovery of the indigenous Chiren gas-field in 1967. The first agreement with the ex-USSR for supply of natural gas and construction of main pipelines was signed in 1968. The state gas company BULGARGAZ is responsible for transportation, storage, distribution, processing and marketing of the gas to over 150 industrial companies in the country, as well as for the transportation services to gas importers in neighboring Turkey. The GAZSTROJMONTAZH company accomplish the construction of the local and transit pipelines to Turkey and Greece, as well as of some objects in Iran, Syria, Ukraine and Germany. In the past 20 years, 87890 million m 3 natural gas from Russia are supplied and 846 million m 3 - from domestic sources. The share of natural gas in the overall energy balance is 13.6% for 1992. The restructuring and further development of gas industry require to take into account some factors as: security in supply; investments for technical assurance; pricing policy for natural gas; development of private business. Some administrative problems are also mentioned. 2 tabs., 1 fig

Pt-decorated GaN nanowires with significant improvement in H2 gas-sensing performance at room temperature.

Science.gov (United States)

Abdullah, Q N; Yam, F K; Hassan, Z; Bououdina, M

2015-12-15

Superior sensitivity towards H2 gas was successfully achieved with Pt-decorated GaN nanowires (NWs) gas sensor. GaN NWs were fabricated via chemical vapor deposition (CVD) route. Morphology (field emission scanning electron microscopy and transmission electron microscopy) and crystal structure (high resolution X-ray diffraction) characterizations of the as-synthesized nanostructures demonstrated the formation of GaN NWs having a wurtzite structure, zigzaged shape and an average diameter of 30-166nm. The Pt-decorated GaN NWs sensor shows a high response of 250-2650% upon exposure to H2 gas concentration from 7 to 1000ppm respectively at room temperature (RT), and then increases to about 650-4100% when increasing the operating temperature up to 75°C. The gas-sensing measurements indicated that the Pt-decorated GaN NWs based sensor exhibited efficient detection of H2 at low concentration with excellent sensitivity, repeatability, and free hysteresis phenomena over a period of time of 100min. The large surface-to-volume ratio of GaN NWs and the catalytic activity of Pt metal are the most influential factors leading to the enhancement of H2 gas-sensing performances through the improvement of the interaction between the target molecules (H2) and the sensing NWs surface. The attractive low-cost, low power consumption and high-performance of the resultant decorated GaN NWs gas sensor assure their uppermost potential for H2 gas sensor working at low operating temperature.

The water-gas shift (WGS) reaction is an important step in the purification of hydrogen for fuel cells. It lowers the carbon monoxide content and produces extra hydrogen. The constraints of automotive applications render the commercial WGS catalysts unsuitable. Pt/ceria catalysts are cited as promising catalysts for onboard applications as they are highly active and non-pyrophoric. This paper reports on a power law rate expression for a Pt/CeO{sub 2}/Al{sub 2}O{sub 3} catalyst. This rate equation is used to compare different reactor configurations for an onboard water-gas shift reactor. A one-dimensional heterogeneous model that accounts for the interfacial and intraparticle gradients has been used to optimize a dual stage adiabatic monolith reactor. (author)

FePt bimetallic catalysts with intimate contact between the two metals were synthesized by controlled surface reactions (CSR) of (cyclohexadiene)iron tricarbonyl with hydrogen-treated supported Pt nanoparticles. Adsorption of the iron precursor on a Pt/SiO2 catalyst was studied, showing that the Fe loading could be increased by performing multiple CSR cycles, and the efficiency of this process was linked to the renewal of adsorption sites by a reducing pretreatment. The catalytic activity of these bimetallic catalysts for the water gas shift reaction was improved due to promotion by iron, likely linked to H2O activation on FeOx species at or near the Pt surface, mostly in the (II) oxidation state.

Stability investigation of a high number density Pt1/Fe2O3 single-atom catalyst under different gas environments by HAADF-STEM

Duan, Sibin; Wang, Rongming; Liu, Jingyue

2018-05-01

Catalysis by supported single metal atoms has demonstrated tremendous potential for practical applications due to their unique catalytic properties. Unless they are strongly anchored to the support surfaces, supported single atoms, however, are thermodynamically unstable, which poses a major obstacle for broad applications of single-atom catalysts (SACs). In order to develop strategies to improve the stability of SACs, we need to understand the intrinsic nature of the sintering processes of supported single metal atoms, especially under various gas environments that are relevant to important catalytic reactions. We report on the synthesis of high number density Pt1/Fe2O3 SACs using a facial strong adsorption method and the study of the mobility of these supported Pt single atoms at 250 °C under various gas environments that are relevant to CO oxidation, water–gas shift, and hydrogenation reactions. Under the oxidative gas environment, Fe2O3 supported Pt single atoms are stable even at high temperatures. The presence of either CO or H2 molecules in the gas environment, however, facilitates the movement of the Pt atoms. The strong interaction between CO and Pt weakens the binding between the Pt atoms and the support, facilitating the movement of the Pt single atoms. The dissociation of H2 molecules on the Pt atoms and their subsequent interaction with the oxygen species of the support surfaces dislodge the surface oxygen anchored Pt atoms, resulting in the formation of Pt clusters. The addition of H2O molecules to the CO or H2 significantly accelerates the sintering of the Fe2O3 supported Pt single atoms. An anchoring-site determined sintering mechanism is further proposed, which is related to the metal–support interaction.

Onsite gas storage for industrial customers

International Nuclear Information System (INIS)

Shikari, Y.A.

1990-01-01

The changing pattern of industrial gas marketing in the United States and other countries has placed new pressures on industrial users to assume responsibility for assuring their own supply. Technological changes in manufacturing processes have placed greater emphasis on assuring fuel quality and many processes can no longer tolerate near-substitutes such as distillate fuel oil and LPG. One way to take advantage of lower cost interruptible gas service contracts is to provide stand-by sources of gas onsite which can be used when the primary supply is curtailed. This paper describes the methods which an industrial gas consumer could use to store gas onsite (or close by an industrial factory) and their technical and economic advantages or limitations. The regulatory factors such as environmental and safety issues are reviewed and the advantages and disadvantages of each method are described. The application of emerging technologies such as storing natural gas on adsorbents at low pressure and solid absorption in LPG are reviewed and the research needed to make them acceptable is discussed. The potential applications in the marketplace are also discussed and the economics of onsite storage of natural gas is compared to other alternatives. (author). 11 refs, 5 figs, 1 tab

Expanding Canadian natural gas production will strengthen growth of LP-gas industry

International Nuclear Information System (INIS)

Hawkins, D.J.

1994-01-01

In 1992, over 86% of Canadian propane and 70% of Canadian butane production originated in gas plants. Propane and butane production not recovered at gas plants is recovered in other processing facilities, primarily refineries and heavy oil upgraders. As a result, supplies of both products are largely tied to natural gas production, and the outlook for natural gas therefore provides the basis for any discussion on the outlook for gas processing and NGL industry infrastructure. The paper discusses gas processing, economies of scale, NGL supply, expected declines, industry structure and infrastructure, the two major centers of the Canadian NGL industry, new shippers, and required pipeline expansion

The study reports H{sub 2}S gas sensing characteristics of platinum (Pt) coated porous alumina (PoAl) films. The porous alumina (PoAl) thick layers were formed in the dark on aluminum substrates using an electrochemical anodization method. Thin semitransparent platinum (Pt) films were deposited on PoAl samples using chemical bath deposition (CBD) method. The films were characterized using energy dispersive X-ray analysis (EDAX) and scanning electron microscopy (SEM). The thicknesses of coated and bare films were measured using ellipsometry. The sensing properties such as sensitivity factor (S.F.), response time, recovery time and repeatability were measured using a static gas sensing system for H{sub 2}S gas. The EDAX studies confirmed the purity of Pt–PoAl film and indicated the formation of pure platinum (Pt) phase. The ellipsometry studies revealed the thickness of PoAl layer of about 15–17 μm on aluminum substrates. The SEM studies demonstrated uniform distribution of spherical pores with a size between 0.250 and 0.500 μm for PoAl film and nearly spherical platinum particles with average particle size ∼100 nm for Pt–PoAl film. The gas-sensing properties of these samples were studied in a home-built static gas characterization system. The H{sub 2}S gas sensing properties of Pt–PoAl at 1000 ppm of H{sub 2}S gave maximum sensitivity factor (S.F.) = 1200. The response time and recovery time were found to be 2–3 min and ∼1 min respectively. Further, the measurement of H{sub 2}S gas sensing properties clearly indicated the repeatability of gas sensing response of Pt–PoAl film. The present study indicated the significant potential of Pt coated PoAl films for H{sub 2}S gas sensing applications in diverse areas. - Highlights: • Electrochemical anodization, cheap and effective method for fabrication of PoAl. • Chemical bath deposition, a simple and effective method for deposition of Pt on PoAl. • A nano-composite film sensor with high sensitivity

Natural gas as raw material for industrial development

Kvisle, Steinar

2006-01-01

Industrial development based on natural gas has broad, industrial implications. Norway has a vital industry based on natural gas as raw material, here under Ormen Lange, Snoehvit LNG, Tjeldbergodden and Petrochemical Grenland. The petrochemical industry has challenges, e.g. the cost of raw materials and energy, localization related to the markets, and recruitment, but considerable investments are made in the sector. The Northern areas in Norway may have special challenges related to bringing the product to the market. Solutions to this challenge are in LNG (liquid natural gas), GTL (gas to liquids), and GTO (gas to olefins)

A self-powered gas sensor that can actively detect ethanol at room temperature has been realized from a Pt/ZnO nanoarray nanogenerator. Pt nanoparticles are uniformly distributed on the whole surface of ZnO nanowires. The piezoelectric output of Pt/ZnO nanoarrays can act not only as a power source, but also as a response signal to ethanol at room temperature. Upon exposure to dry air and 1500 ppm ethanol at room temperature, the piezoelectric output of the device under the same compressive strain is 0.672 and 0.419 V, respectively. Moreover, a linear dependence of the sensitivity on the ethanol concentration is observed. Such a linear ethanol sensing at room temperature can be attributed to the atmosphere-dependent variety of the screen effect on the piezoelectric output of ZnO nanowires, the catalytic properties of Pt nanoparticles, and the Schottky barriers at Pt/ZnO interfaces. The present results can stimulate research in the direction of designing new material systems for self-powered room-temperature gas sensing.

Electron beam-induced deposition (EBID) is a direct write process where an electron beam locally decomposes a precursor gas leaving behind non-volatile deposits. It is a fast and relatively in-expensive method designed to develop conductive (metal) or isolating (oxide) nanostructures. Unfortunately the EBID process results in deposition of metal nanostructures with relatively high resistivity because the gas precursors employed are hydrocarbon based. We have developed deposition protocols using novel gas-injector system (GIS) with a carbon free Pt precursor. Interconnect type structures were deposited on preformed metal architectures. The obtained structures were analysed by cross-sectional TEM and their electrical properties were analysed ex-situ using four point probe electrical tests. The results suggest that both the structural and electrical characteristics differ significantly from those of Pt interconnects deposited by conventional hydrocarbon based precursors, and show great promise for the development of low resistivity electrical contacts.

Rising natural gas prices : impacts on U.S. industries

International Nuclear Information System (INIS)

Henry, D.

2005-01-01

The impact of rising natural gas prices on the United States economy and domestic industries was examined in this PowerPoint presentation. Industry comments were solicited on the effects of natural gas prices on their business performance from 2000 to 2004 in order to collect data, and macroeconomic impacts were determined through the use of an inter-industry model. Results of the survey and subsequent model suggested that in 2000 and 2001, real gross domestic product (GDP) growth was depressed by 0.2 per cent because of higher natural gas prices. Between 2000 and 2004, the civilian workforce was lower by 489,000 jobs. It was determined that nitrogenous fertilizer manufacturing was the most gas intensive industry. The results indicated that higher natural gas prices were an additional burden on manufacturing industries, and that the economic performance of natural gas intensive industries was poor between 2000-2004. However, it was just as poor between 1997-2000, when gas prices were relatively low and stable. Natural gas intensive industries passed along price increases in their products to their downstream consumers. Despite job losses, wages in natural gas intensive industries were higher and grew faster than in the rest of the manufacturing industry in the 2000-2004 period. Although capital expenditures declined between 2000 to 2004, they declined more rapidly in the 1997-2000 period. There has been no evidence of a decline in international competitiveness of natural gas intensive industries. It was concluded that rising natural gas prices have had a significant impact on the growth of the economy and workforce. tabs., figs

Polymer electrolyte fuel cells (PEFCs) are suited for use in commercial electrical vehicle and electric power applications. The gas diffusion electrodes of PEFCs are catalyzed by the deposition of platinum (Pt) nanoparticles on carbon powder. The particles must be localized on the electrode surface in order to achieve high electrocatalyst utilization. This study discussed a method of preparing PEFC electrodes using sputter deposition of a Pt-gold (Au) alloy nanoparticles on carbon powders. The method was designed to improve electrode performance and catalyst utilization. The nano-sized alloy clusters were deposited on a gas diffusion electrode at room temperature. The deposits were then characterized using field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS) in order to examine the effect of the deposition technique on the nano-morphology and electrocatalytic performance of the electrode. Results of the study showed that the technique can be used in the large-scale manufacture of fuel cell electrodes. 3 refs., 1 fig.

McDonald, Rob

1994-01-01

This article evaluates the performance of the Australian oil and gas industry, focusing on the listed companies. A large part of the Australian oil and gas industry-(as much as 60 per cent)-is held by unlisted companies or by major international groups not listed in Australia. Nevertheless, it was considered that the sample of companies reviewed gives a reasonable guide to overall industry performance. Also, as part of this relative analysis, the Australian oil and gas industry will be compared to other investments that shareholders could have enjoyed. As well, its performance will be compared with the much larger industry in the United States. It is shown that over the past 10 to 20 years, the rate of return that the Australian oil and gas industry has offered to providers of equity capital has been less than industry expectations. While it was a better performer than the smaller US companies, it lagged substantially behind the major three sectors of the US index, which are international integrated gas distribution and domestic. 10 figs

Challenges and opportunities await natural gas industry

International Nuclear Information System (INIS)

Mohasseb, S.

1998-01-01

During the last two decades, the natural gas industry has gone through drastic changes. On one hand, deregulation and customer choice have been introduced to the industry. On the other hand, technological advances have resulted in substantial growth of available gas resources. In short, deregulation coupled with increased availability of supply has changed the way market participants interact with each other and which avenues they take to become leaders. Many new opportunities for entry into the market have also been created. As a result, the tide of competition has not only turned against the financially strong giants of the past, but it has also turned against new entrants who are fast, flexible and market driven. Natural gas utilities companies have responded by improving their operational efficiencies through process re-engineering, organizational re-alignment, restructuring and strategic alliances or mergers. Deregulation of the electricity industry is expected to increase competitive pressures on the natural gas industry, thus causing even more of a decrease in natural gas prices. In the future, natural gas utilities must be able to improve their effectiveness by accurately forecasting demand and optimizing their own supply and delivery systems in such a way that costs are minimized without compromising the reliability of supply. The new frontier of competitiveness will ensure that structural changes in the industry are characterized by an effective management of the supply-demand relationship and the optimization of risks inherently a part of gas delivery

2003-01-01

An update of the Canadian petroleum and natural gas industry was presented with reference to activity trends and major issues. The presentation also described opportunities and challenges facing the industry in British Columbia and reviewed the impact of federal policies on BC. In recent years the industry has moved to oil sands and unconventional gas, offshore sites, and coalbed methane development. Other changes are a result of technology which makes it possible to drill deeper and faster while having less environmental impact. Government issues have become increasingly complex, however. Industry capital spending from 2000 to 2003 was presented for Northern Canada, the east coast offshore, Alberta, the Western Canada Sedimentary Basin, oil sand deposits, and international activities. The presentation included several graphs depicting: the changing natural gas production mix; North American natural gas demand; wells drilled by province; natural gas resources in BC; upstream capital spending in BC; wells drilled by type and depth in BC; top natural gas wells in 2000 and 2002; natural gas production in BC; finding and development costs for Canadian natural gas; and, the widening gap of the federal income tax rate between oil and natural gas and other industries. British Columbia is in the strategic position of having significant untapped gas potential in the northeastern part of the province. For now, there is sufficient pipeline capacity to bring the gas to markets in the United States where there is a strong demand for electric power generation. 16 figs

Interfacial-Bonding-Regulated CO Oxidation over Pt Atoms Immobilized on Gas-Exfoliated Hexagonal Boron Nitride

KAUST Repository

Liu, Xin

2017-10-12

We compared the electronic structure and CO oxidation mechanisms over Pt atoms immobilized by both B-vacancies and N-vacancies on gas-exfoliated hexagonal boron nitride. We showed that chemical bonds are formed between the B atoms associated with dangling bonds around the vacancies and Pt atoms. These bonds not only alter the thermodynamics and kinetics for the aggregation and effectively immobilize Pt atoms, but also significantly change the composition and energetic distribution of the electronic states of the composites to circumvent CO poisoning and to favour coadsorption of CO and O2, which further regulates the reactions to proceed through a Langmuir-Hinshelwood mechanism. The CO oxidation over Pt atoms immobilized at N-vacancies involves formation of an intermediate with –C(O)-O−O- bonded to Pt, the generation of CO2 by peroxo O−O bond scission and the reduction of the remnant oxygen, and the calculated energy barriers are 0.49, 0.23 and 0.18 eV, respectively. Such small energy barriers are comparable to those over Pt atoms trapped at B-vacancies, showing the effectiveness of Pt/hexagonal boron nitride atomic composites as catalysts for CO oxidation. These findings also suggest the feasibility of regulating the reaction pathways over single atom catalysts via interfacial engineering.

1994-01-01

Information is provided on the availability and cost of natural gas in British Columbia for use by firms interested in establishing gas-intensive industrial facilities in the province. British Columbia has an abundant supply of natural gas, originating mainly from deposits in the westernmost part of the Western Canadian Sedimentary Basin in the northeast part of the province. Recoverable resources in British Columbia are estimated at 1,000-1,400 billion m 3 . Over 200 producers compete to sell natural gas for both domestic and export markets. Gathering, processing, and transmission of the gas is undertaken mainly by the Westcoast Energy pipeline system, and distribution is undertaken by several distribution utilities. At present, all large industrial gas users buy their firm gas requirements directly from gas producers, often using gas marketers or brokers to assist in purchasing. Regulation of the gas industry is performed by the British Columbia Utilities Commission, which sets rules for energy supply contracts, and by the National Energy Board, which sets tolls for gathering, processing, and transporting gas. Factors affecting gas pricing are discussed, with reference to both the wellhead price and the cost of gathering, processing, and transportation. Firm gas costs for two hypothetical industrial loads in British Columbia are illustrated. Potential intensive uses of natural gas in the province are outlined, including power generation, liquefaction for export, manufacturing, production of direct reduced iron, and as petrochemical feedstocks. 5 figs., 2 tabs

Stedman, C.

1998-01-01

Development of a natural gas industry on Canada's east coast was discussed. The various stages of near-term and long-term development were outlined. Opportunities were identified in the areas of Grand Banks gas utilization, third party gas and natural gas liquids transportation and processing, cogeneration, petrochemicals and in energy marketing and services. As an example of this industry development, a corporate review of Novagas Canada Ltd., was presented. The company was formed in January 1994 and is wholly owned by Nova Gas International. Novagas Canada has ultimate resources of 62.9 Tcf of natural gas of which 48.9 Tcf remains to be discovered. The company focuses on non-regulated mid-stream operations of the natural gas/natural gas liquid value chain. Some 800 million dollars have been invested so far in gas processing, liquids and olefins businesses in Nova Scotia and the Grand Banks/Labrador area. The pending Nova/TCPL merger will combine Novagas Canada's and TransCanada Gas Services' midstream assets. The general conclusion was that the resource base is large enough to support development throughout the gas and natural gas liquids value chain, and that a critical mass is required to support development of the necessary gas infrastructure. A sizeable challenge remains in encouraging gas utilization, and in encouraging competition, open access and unbundling of energy services. 2 tabs., 2 figs

The gas industry in Japan

Jego, H.

Though oil is the most widely used primary energy in Japan, its market share is decreasing steadily in favour of other energies such as natural gas. Around 80 % of the gas consumed in Japan is imported in the form of LNG, with locally produced natural gas accounting for 5 % and LPG 12%. Annual LNG supplies now total 48 million tons (720 TWh) and are forecast to rise to 57 million tons over the next ten years. However, only on third of the total volume of LNG, i.e., 242 TWh, is distributed to final consumers. The rest is imported directly by power companies to produce electricity. The 245 gas distribution companies, 70 in the public sector and 175 in the private sector (including three large firms: Tokyo Gas, Osaka Gas and Toho Gas) carry the gas through their own non-interconnected networks to around 25 million customers, though the gas supply area covers only 5 % of the country. This small percentage can be explained partly by Japan's topography: 80 % of the land is covered by mountains. This means that only 20 % of the country is suitable for industrial and residential development. Populations living outside the gas supply areas mainly use LPG. The number of LPG customers totals around 25 million, a similar number to those using mains gas. However, the share of mains gas is increasing each year due to the population increase in urban zones. Though gas represents only 11 % of the energy consumed in Japan, it is nevertheless present on practically all markets and holds the leading position for domestic hot water and cooking in the residential sector. However, for heating, it lags well behind oil. In industry, mains gas covers only 5% of energy needs. However, with the expansion of the pipeline network and market liberalization, the share of gas is set to increase. The price of gas for the residential sector is 2 to 3 times higher than in western countries. This can be attributed to the following factors: most natural gas is imported LNG; unit consumption in the

Natural Gas Liberalisation and Deregulation - The German Gas Industry's View

2001-01-01

In Europe, the process of creating a single energy market is under way. The 1998 Gas Directive established an important date for the European gas industry. On 10 August 1998, ''Directive 98/30/EC of the European Parliament and of the Council of 22 June 1998 concerning common rules for the internal market in natural gas'' came into force. It had to be transposed into national law by the EU member states within two years, i.e. by 10 August 2000. The Directive is a cornerstone in establishing a competitive gas market in the European Union. It is the outcome of several years of negotiations and can be regarded as a compromise between the various interests. On the whole, it leaves EU member states with sufficient scope for adequately taking account of national characteristics in keeping with the principle of subsidiarity. The process of transposing the Gas Directive into the national law of individual EU member states is being closely followed by the European Commission. While acknowledging all the progress made in the single market process, the Commission still detects shortcomings in the implementation of the Gas Directive on the road to an actual single market. This is seen as a justification for new initiatives and intervention, even though the new political framework for the gas industry has not yet been tested in practice and been able to prove itself on a broad scale for any length of time. In the debate on liberalisation, tried-and-tested instruments of secure and market-oriented gas supply on the European continent long-term supply contracts with take-or-pay clauses and competitive oil-indexed gas prices have also come under scrutiny. However, even under the conditions of liberalisation, security of supply has to be achieved mainly by a balanced mix of supply sources and by long-term supply contracts, including competitive pricing as ensured by so-called oil indexing. In the further liberalisation of west European gas industries, it will be essential to ensure

Gas industry development in Egypt

Egypt is a country with major gas potential and its gas industry has grown rapidly over the last ten years. Proven natural gas reserves total an estimated 1,050 billion m 3 . According to the re-evaluation of reserves made in January 2000, probable reserves stand at 3,400 billion m 3 , placing Egypt in ninth position as a potential world producer. These reserves are contained in 120 fields located mainly in the Nile Delta and Mediterranean regions and, to a lesser extent, in the Western Desert and the Gulf of Suez. Over the last two years, 54 new gas field have been discovered and registered. Consumption of oil, Egypt's main primary energy source, has declined steadily since the early 1980's in favour of natural gas, which has enjoyed steady growth. The penetration of natural gas is due to the growth of industries consuming large quantities of gas (chemical, fertilizers, etc), the development of new gas fields and the use of gas as a substitute for oil and coal, especially in the power industry which accounts for a major share of energy consumption, i.e., two-thirds of production in 1997. However, as Egypt is currently neither an importer or exporter of natural gas, the growth in consumption has naturally followed that of production, and the lack of infrastructure explains the limited penetration of gas in the residential sector (less than 2 % in 1997). According to the gas development plan drawn up by the Egyptian authorities, internal consumption should increase from 13.5 billion m 3 per year in 1998 to around 45.5 billion m 3 per year in 2017. This consumption increase will be accelerated to respond to domestic needs and, in particular, to favour the implementation of the national redevelopment plan (distribution of the population over 25% of the country by 2020, compared to 4% day). The energy vector of this urban policy is gas. Moreover, this policy should offset the drop in income resulting from declining oil production. The Egyptian authorities, via a range

We report the formation of very uniform and smooth Ni(Pt)Si on epitaxially grown SiGe using Si gas cluster ion beam treatment after metal-rich silicide formation. The gas cluster ion implantation process was optimized to infuse Si into the metal-rich silicide layer and lowered the NiSi nucleation temperature significantly according to in situ X-ray diffraction measurements. This novel method which leads to more uniform films can also be used to control silicide depth in ultra-shallow junctions, especially for high Ge containing devices, where silicidation is problematic as it leads to much rougher interfaces.

Written by experts. Richly illustrated. Encourages future research and investments in the fascinating field of gas sensors. Gas sensor products are very often the key to innovations in the fields of comfort, security, health, environment, and energy savings. This compendium focuses on what the research community labels as solid state gas sensors, where a gas directly changes the electrical properties of a solid, serving as the primary signal for the transducer. It starts with a visionary approach to how life in future buildings can benefit from the power of gas sensors. The requirements for various applications, such as for example the automotive industry, are then discussed in several chapters. Further contributions highlight current trends in new sensing principles, such as the use of nanomaterials and how to use new sensing principles for innovative applications in e.g. meteorology. So as to bring together the views of all the different groups needed to produce new gas sensing applications, renowned industrial and academic representatives report on their experiences and expectations in research, applications and industrialisation.

Sintering of Pt nanoparticles via volatile PtO_2: Simulation and comparison with experiments

International Nuclear Information System (INIS)

Plessow, Philipp N.; Abild-Pedersen, Frank

2016-01-01

It is a longstanding question whether sintering of platinum under oxidizing conditions is mediated by surface migration of Pt species or through the gas phase, by PtO_2(g). Clearly, a rational approach to avoid sintering requires understanding the underlying mechanism. A basic theory for the simulation of ripening through the vapor phase has been derived by Wynblatt and Gjostein. Recent modeling efforts, however, have focused entirely on surface-mediated ripening. In this work, we explicitly model ripening through PtO_2(g) and study how oxygen pressure, temperature, and shape of the particle size distribution affect sintering. On the basis of the available data on α-quartz, adsorption of monomeric Pt species on the support is extremely weak and has therefore not been explicitly simulated, while this may be important for more strongly interacting supports. Our simulations clearly show that ripening through the gas phase is predicted to be relevant. Assuming clean Pt particles, sintering is generally overestimated. This can be remedied by explicitly including oxygen coverage effects that lower both surface free energies and the sticking coefficient of PtO_2(g). Additionally, mass-transport limitations in the gas phase may play a role. Using a parameterization that accounts for these effects, we can quantitatively reproduce a number of experiments from the literature, including pressure and temperature dependence. Lastly, this substantiates the hypothesis of ripening via PtO_2(g) as an alternative to surface-mediated ripening.

The rebirth of natural gas industry in North America

1994-01-01

In seventies years united states of america made a strict regulation of gas prices; as a matter of results, producers were discouraged and did not engaged themselves in gad prospecting and production. In eighties years began the deregulation and that what gave to producers the stimulation to prospect and produce. It is necessary to increase the efficiency of gas and then the gas industry will develop more and more. An other point made to favour gas industry is the performance from an ecological point of view. It is easy to understand why gas industry has a development three times more important than others energy sources

Regeneration of Pt-catalysts deactivated in municipal waste flue gas with H2/N2 and the effect of regeneration step on the SCR catalyst

DEFF Research Database (Denmark)

Due-Hansen, Johannes; Rasmussen, Søren Birk; Kustov, Arkadii

Municipal waste flue gas was previously found to deactivate the Pt-based CO oxidation catalyst severely. In the specific case studied, siloxanes were found to cause the deactivation. An on-site method for complete regeneration of the catalyst activity was found without shutdown of the flue gas...... stream, i.e. by in situ treatment of the Pt-catalyst by reductive H2-gas. However, introduction of H2 gas in the gas stream could also affect other units in the tail pipe gas cleaning system. Of special interest here, is the effect of hydrogen gas on the performance of the deNOx + SCR catalytic process...

Gas and power industries linking as regulation fades

Although the gas and electricity markets have their organizational and operational idiosyncrasies, the principles of a competitive market apply to both. The gas industry model of functional and services unbundling, and the elimination of the pipeline merchant function should be emulated. This process of one industry learning from another is inevitable as electricity and natural gas come to be traded in a nearly unified energy market. As their markets merge, two once-distinct industries will be come much more alike, each borrowing the best features of the other and leaving less-desirable features behind. Factors are discussed

Raman Spectroscopy and Electrochemical Investigations of Pt Electrocatalyst Supported on Carbon Prepared through Plasma Pyrolysis of Natural Gas

2015-01-01

Full Text Available Physicochemical and electrochemical characterisations of Pt-based electrocatalysts supported on carbon (Vulcan carbon, C1, and carbon produced by plasma pyrolysis of natural gas, C2 toward ethanol electrooxidation were investigated. The Pt20/C180 and Pt20/C280 electrocatalysts were prepared by thermal decomposition of polymeric precursors at 350°C. The electrochemical and physicochemical characterisations of the electrocatalysts were performed by means of X-ray diffraction (XRD, transmission electron microscope (TEM, Raman scattering, cyclic voltammetry, and chronoamperometry tests. The XRD results show that the Pt-based electrocatalysts present platinum metallic which is face-centered cubic structure. The results indicate that the Pt20/C180 electrocatalyst has a smaller particle size (10.1–6.9 nm compared with the Pt20/C280 electrocatalyst; however, the Pt20/C280 particle sizes are similar (12.8–10.4 nm and almost independent of the reflection planes, which suggests that the Pt crystallites grow with a radial shape. Raman results reveal that both Vulcan carbon and plasma carbon are graphite-like materials consisting mostly of sp2 carbon. Cyclic voltammetry and chronoamperometry data obtained in this study indicate that the deposition of Pt on plasma carbon increases its electrocatalytic activity toward ethanol oxidation reaction.

Lessons learned from Brazilian natural gas industry reform

International Nuclear Information System (INIS)

Mathias, Melissa Cristina; Szklo, Alexandre

2007-01-01

Over the past decades many countries have reformed their infrastructure industries. Although these reforms have been broadly similar for the most part, aiming at introducing competition in potentially competitive segments, the contexts in which they have been carried out differ. This is due to the past regulatory experience in each country, the maturity of the industry and/or the number of agents when the reform process started. The Brazilian natural gas reform stands out due to the country's singular conditions. The development of the natural gas industry in Brazil was grounded on stepping up supplies through integration with neighboring nations (particularly Bolivia) and establishing a competitive environment by lowering the barriers hampering the arrival of new investors. However, natural gas is located at the crossroads of two main energy chains: oil and hydroelectricity. This article analyzes the Brazilian natural gas reform, and extracts lessons from this process. The low capillarity of transportation and distribution systems continues to be the main bottleneck of the country's natural gas industry. The challenges of the new legal framework are to encourage investments in networks and guarantee supply, to allow the industry to consolidate and mature, against a backdrop of rapid changes in the world market.

Deregulation, market structure and gas prices in the Canadian Natural Gas Industry

International Nuclear Information System (INIS)

Uhler, R.S.

1992-01-01

During the course of the development of the natural gas industry in Canada, gas purchase and sales markets have evolved from being relatively free of regulation to being highly regulated and back again. Though pipeline transport charges were regulated, the pipeline companies, or their subsidiaries, owned the gas that they transported and price and other provisions of purchase and sales contracts were freely negotiated with the producers at one end and distributing utilities or industrial users at the other end. The Western Accord of 1985 set the process of deregulation of the Canadian natural gas industry in motion. On November 1, 1986, natural gas prices in interprovincial trade were deregulated in that domestic natural gas prices were to be freely negotiated. Although not stated explicitly, government policy is to permit export prices to be freely negotiated so long as they do not fall below domestic prices. The deregulation process has dramatically changed the relationship between buyers and sellers. Of particular importance is that deregulation has permitted companies to negotiate gas purchase contracts directly with producers with the pipeline company acting solely as a gas transporter. The purpose of this paper is to examine the forces that have led to shorter term contracts and to examine the likely effect of these contract terms on reservoir development investment incentives. 5 refs., 3 figs

Even though conversion of oil based fuel (Bahan Bakar Minyak) into gas fuel (Bahan Bakar Gas) for transportation (both land and sea) is one of the priority programs of the government of Indonesia, rules that have been established merely basic rules of gas fuel usage license for transportation, without discussing position of gas fuel related to oil based fuel in detail. This paper focus on possible strategic behavior of the key players in the oil-gas fuel conversion game, who will be impacted by the position of gas fuel as complement or substitution of oil based fuel. These players include industry of oil based fuel, industry of gas fuel, and the government. Modeling is made based on two different conditions: government plays a passive role and government plays an active role in legislating additional rules that may benefit industry of gas fuel. Results obtained under a passive government is that industry of oil based fuel need to accommodate the presence of industry of gas fuel, and industry of gas fuel does not kill/ eliminate the oil based fuel, or gas fuel serves as a complement. While in an active government, the industry of oil based fuel need to increase its negotiation spending in the first phase so that the additional rule that benefitting industry of gas fuel would not be legislated, while industry of gas fuel chooses to indifferent; however, in the last stage, gas fuel turned to be competitive or choose its role to be substitution.

The development of the British gas industry shows that structural changes at one industrial stage may have effects on the other stages and that competition at one stage (commercial stage) may be limited by the way the other stages are structured. The conditions of regulation in the gas industry, the development at its different stages, and its present structure are described. The effects of commercial restructuring on gas exploration and gas lifting, gas transport and gas storage are analyzed. (orig./UA) [de

Methane emissions from the natural gas industry

Harrison, M.R.; Cowgill, R.M.; Campbell, L.M.; Lott, R.A.

1993-01-01

The U.S. EPA and the United Nation's Intergovernmental Panel on Climate Change (IPCC) have suggested that global warming could be reduced if more energy was generated using natural gas rather than fuels such as coal. An increased use of natural gas instead of coal would decrease global warming since methane emits less carbon dioxide (CO 2 ) than any fossil fuel. However, methane is a more potent as a greenhouse gas than CO 2 , and leakage from the gas system could reduce or eliminate the inherent advantage of natural gas. For this reason, methane emissions must be quantified before a national policy on preferred fuels is developed. Therefore, GRI and EPA have developed this confunded program to quantify methane emissions from the U.S. gas industry. This paper presents, for general industry review, the approach and methodology that the project is using to determine the emissions. The study will measure or calculate all gas industry methane emissions - from production at the wellhead, through the system, to the customer's meter. When these data are combined with data from other studies, a definitive comparison of the relative environmental impact of using methane versus other fuels will be possible. The study will also provide data that can be used by the industry to identify cost-effective mitigation techniques to reduce losses. The methane emissions project is being conducted in three phases: the first two phases have identified and ranked all known potential methane-emitting sources and established methods for measuring, calculating, and extrapolating emissions from those sources. The third phase, which is currently in progress, will gather sufficient data to achieve the accuracy goal. This paper briefly summarizes the methodology being used for the completion of the third phase

Between 1991 and 1993, the natural gas industry will invest $28.297 billion to install additional facilities for natural gas production and storage, transmission, underground storage, gas distribution and for other general expenditures, estimates the American Gas Association as shown in the 1990 Gas Facts. This is a 38% investment increase from the forecasts in the 1989 Gas Facts. This issue forecasts investments of $13.303 billion for 1991 and $18.396 billion for 1992. This issue does not include investments for 1993. In 1989, (the last figures released) the gas industry invested $7,341 billion for new transmission lines, distribution mains, underground storage, production and storage and general facilities. Included in the 1989 expenditures are: $3.980 billion in distribution facilities; $2.081 billion in gas transmission systems and $159 million in underground storage facilities. Investment in new distribution facilities in 1991 and $4.550 billion in 1993. This is a steady increase for these three years. Investments in natural gas transmission facilities show a steady increase also. In 1991, pipe line operating companies will invest $9.391 billion for new facilities, $9.005 in 1992 and $9.901 billion in 1993

The natural gas industry in Korea has characteristics of a dual industrial structure with wholesale and retail and a regional monopoly of city gas company. Recently there have been discussions on the restructuring of gas industry and the problems arising from such industrial organization. At this point, the labor and capital cost of KOGAS were analyzed to find out efficiency of KOGAS, the wholesaler and the cost function focusing on distribution was estimated to find out effect of scale of city gas company, the retailer. As a result, in the case of KOGAS, it is prove that enhancing competitive power is needed by improving labor productivity through stabilization of labor structure and by maximizing value-added through stability of capital combination. From the estimation of cost function of city gas companies, the existing regional monopoly of city gas company have effects on its scale only when the area of operation and end users used the same amount per end user are increased.

Zhang Zhonghai; Hossain, Md. Faruk.; Arakawa, Takuya; Takahashi, Takakazu

2010-01-01

In this paper, various zinc oxide (ZnO) films are deposited by a versatile and effective dc-reactive facing-target sputtering method. The ratios of Ar to O 2 in the mixture gas are varied from 8:2 to 6:4 at a fixed sputtering pressure of 1.0 Pa. X-ray diffraction, spectrophotometer and scanning electron microscope are used to study the crystal structure, optical property and surface morphology of the as-deposited films. The Pt ultra-thin layer, ∼2 nm thick, is deposited on the surface of ZnO film by dc diode sputtering with a mesh mask controlling the coated area. The photocatalytic activity of ZnO films and Pt-ZnO films is evaluated by decomposition of methanol under UV-vis light irradiation. The variation of photocatalytic activity depends on the ratios of Ar to O 2 , which is mainly attributed to the different grain size and carrier mobility. Though the pure ZnO film normally shows a low gas-phase photocatalytic activity, its activity is significantly enhanced by depositing Pt ultra-thin layer.

What's ahead for the gas industry?

Rogers, B.

1998-01-01

The issue of what is in store for the North American electricity and gas markets was discussed. The electric power and gas industry are moving towards competition which will benefit the majority of market participants and will create a more level playing field. Deregulation in the U.S. natural gas industry is also building momentum. The steps that companies wishing to be successful must take before they can take full advantage of new and emerging opportunities are to: (1) know their business, and recognize that they are in the energy business, not only in the natural gas or electricity business, (2) organize for success by planning for mergers, acquisitions and alliances, (3) manage for change, and (4) know their markets and customers. Deregulation and converging energies were seen as the two major issues that the energy sector in Canada will be facing in the near future. Natural gas and electric utilities will survive beyond the year 2000 if they are flexible, provide a wide range of services, and offer new rates. Ontario Hydro's move to diversify their existing power generation and to burn natural gas for power generation to meet energy demand was considered to be a good example of how to manage for change. tabs., figs

Overview of Gas Research Institute's industrial utilization research and development program

Energy Technology Data Exchange (ETDEWEB)

Tabb, E S

1982-05-01

A combination of technical, economic, political, and environmental constraints hamper industry's ability to use natural gas efficiently. Although the industrial sector has the best potential to absorb the current surplus of natural gas, many industrial users are disenchanged with the high cost, low efficiency, and environmental problems associated with the existing inventory of gas-fired process systems. Consequently, it is essential for an organization like Gas Research Institute (GRI), which has a national scope and a mandate to generate energy end-use benefits for the industrial gas consumer, to assume a leadership role in the development program aimed, not only at upgrading the energy efficiency of industrial process equipment, but at increasing its production capability while meeting environmental standards.

1997-01-01

As in all industrialized countries, in order to keep abreast of the increasing demand for energy and environmental protection requirements, the Canadian gas industry must take up the challenge of the next century and ensure a sustainable economic development in which gas will play an important role. What share of the energy mix for the years to come should be allocated to gas? How should demand be met? What changes should take place in order to be able to offer consumers an energy which is plentiful, safe and cost-effective? How should gas companies organize themselves in market which is becoming more and more de-regulated? Such the themes tackled by Mr Gerard Doucet, President of the Canadian Gas Association, during a presentation which took place at the French Gas Association's executive committee meeting. (author)

Corporate renewal in the natural gas industry

Simpson, B.

1994-01-01

The changes occurring at the gas-related operating companies of Nova Corporation of Alberta are reviewed. These companies include Nova Gas Transmission, Alberta's major gas pipeline company, which moved 3.8 trillion ft 3 of gas in 1993; Nova Gas Services, a provider of gas management services to customers in Canada, USA, and Mexico; and Novacorp International, a joint venture investor in gas pipeline developments and consulting. The changes were made in response to increased competition in the gas transport industry following the deregulation process that started in the mid-1980s. A strategic direction based on growth rather than cost-cutting was chosen in order to make the Nova companies dominant players in North American gas supply. Nova's confidence in being able to implement such a strategy is based on four factors: abundant supply of gas and high potential for growth in the Western Canada Sedimentary Basin; steadily growing demand for gas; the development of a market-responsive industry; and the emergence of a truly North American market that includes Mexico. Business transformation teams were established with the task of finding out the right business design to meet customer needs and to provide exceptional service. Detailed plans for implementing the transformation are being completed, and a performance measurement system with clear targets has been developed to measure the success of the transformation

Overview of the U.S. gas industry

Ramsey, J.

1992-01-01

Natural gas supply and demand is first reviewed in a discussion of the current state of the gas industry in the USA. The deliverability surplus is declining due to factors including a decline in drilling and workover rig activity and a continuing growth in demand at least partly caused by new markets for gas such as gas-fired power generation. The environmental movement, influencing laws favoring clean-burning fuels such as gas, is an additional influence on future demand. A key factor in the gas industry's ability to keep demand growing is how safely and successfully it can implement many aspects of Federal Energy Regulatory Commission Order 636 regarding pipeline restructuring. It is expected that this restructuring will see changes in gas transport and marketing, including an increasing role for supply aggregators and capacity brokers and an abandonment of the merchant function by some pipeline companies. A significant change in the last year or so is that US producers are willing and able to enter into long term supply contracts. Finally, gas production from the Gulf of Mexico basin is expected to continue to produce 2-2.5 trillion ft 3 /y for years to come, despite being a mature area for gas production

Strategic implications of gas to liquids technology for the natural gas industry

Russell, B. J.

1998-01-01

A new and economical gas to liquids (GTL) technology is described that promises to substantially increase industry's ability to exploit many trillions of cubic feet of largely unmarketable reserves of natural gas. The technology turns the gas into a form that overcomes prohibitive transportation costs, avoids long-term, high-risk, take-or-pay contracts, and helps satisfy the demand for cleaner liquid products. Widespread application of GTL technology is credited with having the power to ease the burden on every segment of the petroleum industry, from exploration through petrochemicals, and into allied industries such as electric power generation. It is claimed that in situations where GTL is the only economic option, it will create an entirely new set of opportunities. Among these are the monetization of known stranded gas and the early development of remote gas discoveries or of oil discoveries associated with gas. It will cause a re-evaluation of exploration strategies by upgrading gas prospects in remote locations and new investment options to countries with shut-in gas or heavy oil or tar sand reserves. The monetization of associated gas when reinjection is no longer needed or desired could occur. Extensive applications offshore and adjacent to coastal reserves and multiple options for refiners facing heavier, higher-sulfur crude slates are possible. The outlook for Syntroleum's version of the GTL process, and the 'grant-back' provisions of Syntroleum's license agreements with companies such as Texaco, ARCO, Marathon, Criterion Catalyst, Catalytica, and ABB, giving each licensee access to the improvements of the other licencees, and the joint development agreements with these companies, were also discussed. 6 refs

Gas industries in Europe and America and trends of deregulation; Obei no gas jigyo to kisei kanwa no doko

Santo, Y [Osaka Gas Co. Ltd., Osaka (Japan)

1994-12-01

This paper describes an outline of natural gas industries in Europe and America, introduction of competition to gas industry in the USA, introduction of competition to gas industry in the UK, and gas industries in the continental Europe. For the new gas distribution system in the USA, pipeline enterprises are permitted to do only transportation services. Sale of gas is based on the direct contract between producers and distributors. In the UK, the British Gas Corporation (BGC) was converted into the private British Gas plc (BG) in 1986. With introducing the competition conditions, the BG has drastically modified its organization, to divide it into the domestic gas division, overseas gas division and the division of development and production of gas. As a consequence of the introduction of competition conditions, the market share of BG has drastically decreased. Moreover, gas industries in Germany, France, Italy, Spain, Belgium, Austria and the Netherlands are briefly described. 4 figs.

Panorama 2010: Short-term trends in the gas industry

International Nuclear Information System (INIS)

Lecarpentier, A.

2010-01-01

After a period of strong expansion that lasted for most of 2008, the gas industry was hard hit by the impact of the economic recession. Although the competitiveness of the gas price was often an advantage in 2009, the natural gas market saw a net decline in consumption that led to a historic decrease in world production and international trade. In addition, the subsequent collapse of market prices gave LNG a competitive edge in the Atlantic Basin, where surplus gas continued to accumulate, heralding a long 'gas bubble' period that the industry will have to adjust to permit harmonious, long-term development of the gas markets.

Review of the Soviet gas industry in 1990

International Nuclear Information System (INIS)

Sagers, M.J.

1991-01-01

Soviet production of natural gas increased by only 18.6 billion cubic meters (2.3%) in 1990, from 796.1 billion cubic meters (BCM) to 814.7 BCM. This was the smallest annual increment and the lowest rate of growth in more than two decades. During the 1980s, annual growth typically had been in the 6-8% range, with yearly increments of 40-50 BCM. Of the national total in 1990, enterprises of the Gazprom Concern (formerly the Ministry of the Gas Industry) produced 748.0 BCM, while the Ministry of Oil and Gas produced 66.7 BCM; the latter would be mostly associated gas. Given the USSR's ample resource base, it appears that the Soviet economy is experiencing increasing problems absorbing natural gas, particularly as Soviet aggregate economic output falls along with total energy consumption. During the 1980s, when the gas industry was growing so rapidly, the Soviets absorbed the massive increments in gas supply by directing most of it to a few very large consumers - electric power stations, iron and steel plants, and nitrogenous fertilizer centers. Currently, 54.3% of gas is used for electric power generation; 32.6% in industry; and only 13.1% by the housing and municipal sector. Although the share of housing units using either natural gas or LPG (liquefied petroleum gas-butane and propane) is fairly high in the Soviet Union - 84.8% - this is mostly for cooking rather than heating, so gas use per unit is relatively small. Another problem is that the availability of gas among households is very uneven across the republics and between rural and urban areas. A table gives statistics on gas production in various regions from 1970-1990

Financial outlook for the Canadian gas industry

International Nuclear Information System (INIS)

Friedenberg, B.

1994-01-01

The financial outlook for the Canadian natural gas industry is discussed in terms of the price of Canadian gas and its production and transportation costs. Demand growth for natural gas is fairly steady, reflecting economic growth and technological advances. Supply growth is more volatile, overshooting demand growth in an up market and undershooting in a down market. In the past year and a half, gas prices have improved as the supply deliverability surplus has eroded. It is predicted that supply will again exceed demand and prices will decline, the length of this price cycle being a few years. Production costs for western Canadian gas had been declining during the mid-1980s to 1991, and current replacement costs average ca $1.87/GJ. It is doubtful that fieldgate costs will increase to overtake fieldgate market prices and the Canadian gas industry will remain in a healthy state. The availability and cost of gas transport, however, is critically important. The major costs of pipeline transport are fixed demand charges and the value of transport services out of western Canada is determined by the demand and the supply (the location and size of the pipeline infrastructure, which is essentially fixed over short to medium time frames). This value can vary significantly as the demand for pipeline space varies both daily and seasonally. Excess pipeline capacity is generally good for the Canadian producing industry since it lowers transport costs, but excess capacity also plays a role in linking producing-basin and market area prices to one another. This is illustrated for the case of Alberta and Texas gas prices, which show higher correlation with falling load factors on ex-Alberta pipeline capacity. 5 figs

The paper presents an analysis of tbc effects of tbc European Union (EU) Gas Directive on the EU natural gas industry in the next ten years. First, it briefly reviews the current driving factors for increasing competition in the EU gas markets. Second, the different directions of implementation of EU Gas Directive are discussed. Finally we give an assessment of impacts of the different directions of implementation of the Gas Directive, thereby focusing on structural changes of the gas industry and the scope for reduction of consumer gas prices. Note that our assessment of the impacts is partly based on an analysis of recent trends in the EU gas market and partly on calculations with a recently developed model of the EU gas market on company level. The paper summarises the main observations of a study conducted by the Netherlands Energy Research Foundation (ECN) last year in the framework of a larger scenario study for the European Committee, Directorate-General 17, in the Shared Analysis Project, 'Economic Foundations for Energy Policy in Europe to 2020' managed by FhG-ISI. For the complete results of the ECN study, see report 'Impacts of Market Liberalisation on the EU Gas Industry', September 1999, forthcoming. Note that the analysis is limited to the gas market and does not include other impacts, i.c. on energy conservation, emissions, etc. 21 refs

Natural gas industry and global warming

International Nuclear Information System (INIS)

Staropoli, R.; Darras, M.

1997-01-01

Natural gas has a very good potential compared to other fossil fuels as regard to global warming because of its high content of hydrogen, and its versatility in uses. To take full advantage of this potential, further development of gas designed boilers and furnaces, gas catalytic combustion, fuel cells are needed, but progresses in the recent years have been very promising. The natural gas industry' environmental potential is discussed. Regarding methane emission, progresses have been done is Western Europe on the distribution network, and some improvement are underway. It is however important to rationalize the effort by acting on the most emitting subsystem: this can be achieved by cooperation along the whole gas chain. (R.P.)

Gas-side fouling and corrosion problems occur in all of the energy intensive industries including the chemical, petroleum, primary metals, pulp and paper, glass, cement, foodstuffs, and textile industries. Topics of major interest include: (1) heat exchanger design procedures for gas-side fouling service; (2) gas-side fouling factors which are presently available; (3) startup and shutdown procedures used to minimize the effects of gas-side fouling; (4) gas-side fouling prevention, mitigation, and accommodation techniques; (5) economic impact of gas-side fouling on capital costs, maintenance costs, loss of production, and energy losses; and (6) miscellaneous considerations related to gas-side fouling. The present state-of-the-art for industrial gas-side fouling is summarized by a list of recommendations for further work in this area.

Structural and magnetic properties of FePt nanoparticles from the gas phase; Strukturelle und magnetische Eigenschaften von FePt-Nanopartikeln aus der Gasphase

Energy Technology Data Exchange (ETDEWEB)

Dmitrieva, O.

2007-09-21

In this work, we present the structural and magnetic characterization of FePt nanoparticles. The nanoparticles with mean size of about 6 nm were prepared by sputtering in the gas and subsequent inert gas condensation. The particles are annealed in the furnace during their flight prior to deposition on a substrate. The aim of this work is to prepare magnetically hard FePt nanoparticles in the L1{sub 0}-ordered phase. The structure of the particles was investigated by high-resolution transmission electron microscopy, and the investigations were supported by contrast simulations. The morphology of the particles varies with the sputter-gas pressure and with the annealing temperature. At a pressure of 0.5 mbar, the FePt-nanoparticles are multiply-twinned with an icosahedral structure and exhibit no formation of the L1{sub 0}-ordered phase. At a higher pressure of 1 mbar and an annealing temperature of 1000 C, the particles are partially single-crystalline. About 36 % of the particles are found to be in the L1{sub 0}-ordered state as was estimated by statistical counting supported by simulations. In order to activate the volume diffusion in the particles and to stabilize the formation of the L1{sub 0}-ordered state, the addition of nitrogen was used during the sputtering phase. In this phase, atomic nitrogen is incorporated interstitially into the structure of the primary particles. After annealing nitrogen effuses out of the particles and, thereby, increases the volume diffusion of the Fe and Pt atoms. The incorporation of nitrogen atoms during nucleation and their effusion at an annealing temperature of 1000 C was verified by electron energy loss spectroscopy (EELS) and X-ray absorption spectroscopy (XAS). Structural investigations on particles prepared in the presence of nitrogen shows that most of the particles are single-crystalline and about 70 % of them are L1{sub 0}-ordered. Detailed structural analysis of the nanoparticles was done by the exit wave

1991-01-01

Recent developments in the fabrication of high strength ceramic materials and in their application to automotive and aerospace gas turbine engines may lead also to significant improvements in the performance of industrial gas turbines. This paper presents a brief review of the improvements projected in a study initiated by the U.S. Department of Energy. The future costs of power generated by small gas turbines (up to 25 MW) are predicted, as well as the potential for fuel savings. Gas turbines in this size range are used extensively for gas compression and for cogeneration, as well as in a variety of more diverse applications. This paper includes results of analyses of the ways in which changes in gas turbine cost and performance are likely to affect market penetration. These results lead to predictions of future savings in U.S. fuel consumption in the industrial sector that would result. The paper also presents a brief overview of the scope of a suggested R and D program, with an appropriate schedule, which would provide a technical basis for achieving the projected results. Important parts of this program would cover ceramic design and fabrication technology, engine development and demonstration, and combustion technology

With the significant economic growth in China, energy related environmental issues become more and more serious. Most of air pollutants are produced by burning coal. In order to achieve a sustainable balance between economic growth and environmental protection, China has been taking measures to expand the role played by natural gas, especially since the beginning of the 21st century. As the liquid form of natural gas, liquefied natural gas (LNG) has also been paid more attention in the country. This paper explores main motives for the fast development of China's LNG industry. An overview of the industry is also described, covering LNG receiving terminals, plants and transportation. Despite a relatively short development history of LNG industry in China, there are many remarkable successes. City-gas supply by LNG is widely applied in many small to medium cities, and LNG vehicles and cold energy utilization are growing rapidly with governmental supports. At the end, the developmental trends of China's LNG industry are introduced. All the discussions show that LNG is strategically important in China's future energy infrastructure. - Research highlights: →Explore main momentums for the fast development of China's LNG industry→Analyze detailedly current states and future prospects of LNG infrastructure in China→Introduce and analyze the wide application of LNG-based gas supply mode in China→Discuss new developmental trends in China's LNG industry

In this study we attempted to obtain a Pd-Pt alloy on alumina (PPA) by using an impregnation and alcohol reduction method for the purpose of a hydrogen isotopes separation, in which {alpha}-alumina powder was impregnated into an ethanol water (1/1, w/w) solution containing PdCl{sub 2}, PtCl{sub 2}, and polyvinylpyrrolidone (PVP, MW = 10,000). The sample was dried, reduced by hydrogen, and thermally treated at 1073 K. Thus, two kinds of PPA (Pd content 17 and 29 wt%) were achieved. The produced PPA showed a good crystallinity from the XRD analysis and it exhibited an adequate hydrogen desorption isotherm as a packing material for the separation of hydrogen isotopes. GC columns packed with PPA and Cu powder were used for the separation of a 29.2% D{sub 2}-H{sub 2} gas mixture at 303 and 343 K. The experimental result showed a good separation efficiency of the hydrogen isotopes for the GC process. Consequently, the suggested technique for the production of a Pd-Pt alloy on alumina was proven to be successful.

Klass, D.L.; Khan, R.A.; Khwaja, S.

1992-01-01

The domestic natural gas industry has generally exhibited slow growth in most developing countries that are fortunate enough to have sufficient proved gas reserves to meet energy needs. But supportive government policies that promote the use of indigenous reserves are now beginning to have a positive impact in many parts of the world. Supply and distribution infrastructures are being built or modernized. And natural gas is now or will be available at prices that encourage the displacement of competitive fuels in the larger, energy-intensive industrial and power-generation markets of these countries. It is expected that the domestic gas industry in many developing countries will expand at higher rates than in the past. In the next few decades, the resulting benefits will include reductions in oil consumption per capita, improvements in the balance of payments for oil-importing and exporting developing countries, greater efficiency of energy usage and lower energy consumption per output unit, and improved environmental quality. The national economies and living standards will also undergo significant advancement

Choi, In Dae; Lee, Dong Geun

2008-01-01

Carbon black, activated carbon and carbon nanotube have been used as supporting materials for precious metal catalysts used in fuel cell electrodes. One-step flame synthesis method is used to coat 2-5nm Pt dots on flame-generated carbon particles. By adjusting flame temperature, gas flow rates and resident time of particles in flame, we can obtain Pt/C nano catalyst-support composite particles. Additional injection of hydrogen gas facilitates pyrolysis of Pt precursor in flame. The size of as-incepted Pt dots increases along the flame due to longer resident time and sintering in high temperature flame. Surface coverage and dispersion of the Pt dots is varied at different sampling heights and confirmed by Transmission Electron Microscopy (TEM), Energy Dispersive Spectra (EDS) and X-Ray Diffraction (XRD). Crystallinity and surface bonding groups of carbon are investigated through X-ray Photoelectron Spectroscoy (XPS) and Raman spectroscopy

Full Text Available Natural gas has become more and more important in the world energy market with the change of energy consumption structure and consumption subjects. This paper applies the panel smooth transition regression (PSTR model to study the nonlinear relationship between natural gas consumption and economic variables of emerging economies, and the empirical results show that: (1 There is a non-linear relationship among natural gas consumption, GDP per capita, industrialization and urbanization rate; (2 The optimal PSTR model is a two-regime model by using the lagged industrialization as a transition variable, and the impact of GDP per capita and of industrialization on natural gas consumption shows incomplete symmetry in low and high regime, respectively; (3 The result of time-varying elasticity analysis indicates that natural gas consumption is inelastic to GDP per capita, but elastic to both industrialization and urbanization. The elasticity of GDP per capita generally decrease with fluctuation, the elasticity of industrialization tends to rise, and the elasticity of urbanization is linear at high level; (4 Regional difference shows that there are 10 emerging economies are in first regime (below industrialization of 43.2%, and the remaining 6 are in second regime. This provides reference for countries in different transformation periods to make economic policies adapting to energy saving, energy structure optimization and other sustainable development strategies.

The natural gas industry in Russia: reforms in debate

Locatelli, Catherine

2014-07-01

Due to the emergence of shale gas in the USA, Russia has become the second world producer of natural gas but this industry remains one of the most important sectors of the Russian economy as natural gas exports are an essential component or the Russian economic policy. Addressing this industry, the author first comments the evolutions of gas production since 1960 and its perspectives by 2020 and 2030. He also outlines the importance of the cost issue associated with the choice between mega projects and smaller ones. In a second part, the author comments and discusses the evolutions of gas exports towards Europe and of the export strategy. He evokes the possibility of arbitration between price and quantity in Gazprom's strategy, the possibility of a strategy of downstream integration on European gas markets, the possibility of a diversification of export markets (notably LNG markets as several LNG projects are planned). In the third part, the author describes the Gazprom model, comments the recurring debate on a reform of this holding, and discusses its quantity-based management and the issue of Gazprom's efficiency. He briefly evokes the issue of reform of the Russian gas industry, the progressive emergence of new actors

The stability and dynamics of Pt dimers on Pt(110)-(1x2) are studied using fast-scanning, variable-temperature STM. The kinetics of both dissociation and association of dimers have been quantified from a direct analysis of time-lapse STM movies. The extracted barriers are at variance with results from ab initio calculations, and we speculate that the discrepancies are due to trace amounts of gas impurities such as CO

Policy subjects of the LP gas industry; LP gas sangyo no seisaku kadai

Murata, K. [Agency of Natural Resources and Energy, Tokyo (Japan)

1996-09-01

The paper commented on current environmental changes in the LP gas industry and the measures for reinforcement of the physical constitution. When correction of the high cost structure in Japan is now the problem, waves of deregulation and rationalization reach to not only to LP gas but energy competitive with LP gas such as petroleum, electric power and town gas. With this, it is expected that LP gas will be faced with severe competition with other energy media. In the LP gas industry, business becomes more and more in number and smaller and smaller in scale as it extends downstream. Therefore, the resulting complicatedness in the distribution sector is the problem. It is necessary to realize scale profit in each distribution stage and to heighten productivity by expanding the scale in the retailing stage, especially. It is also important to tackle scale merit, improvement of productivity, and cost reduction by concentrating functions on either of wholesalers or retailers in every function of delivery, safety, free from each distribution stage.

The European Internal Market for natural gas is drawing near, and although the European Directive passed on 11 May 1998 provides for step-wise deregulation, it is expected that in Germany the phase of transition for the gas industry will be as comparatively short as it was for the electric power industry. The contribution here is intended to outline the expected consequences for the gas industry in EC member states and particularly in Germany, and to indicate strategies for managing upcoming risks. The instruments discussed in the article will gain in importance with increasing liberalisation of the markets. (orig./CB) [de

Radiation protection programme in the oil and gas industry

International Nuclear Information System (INIS)

Essien, E. C.

2014-04-01

The oil and gas industry uses many radiation sources in various radiation based technologies which are of great benefit to the industry, this includes nucleonic gauges, multiphase flow meters, well logging etc. Inappropriate use of these equipment and installations and uncontrolled activities associated with naturally occurring radioactive materials (NORM) can contaminate the environment resulting in occupational and public exposures. The objective of this work is to develop a Radiation Protection Programme (RPP) for the oil and gas industry which when implemented by the operating organisation will keep doses to the workers and public as low as reasonably achievable (ALARA), maximize the benefits while minimizing the hazards associated with the use of radiation based technologies. In order to achieve the aim of this work, review of previous works on radiation sources in nucleonic gauges, well logging and waste management processes of NORMs was carried out. Some recommendations were stated, which if strictly implemented would improve the scope of radiation protection in the oil and gas industries. (au)

Panorama 2011: Short-term trends in the gas industry

Lecarpentier, A.

2011-01-01

2009 was a particularly bad year for the natural gas industry, with demand falling dramatically by 2.8% as a result of the world economic crisis. However, 2010 appears to have been a very positive year for the industry, with a sustained increase in production and trade. Increased economic activity, together with harsh winters and competitive gas prices are the reasons for the markets having rediscovered their buoyancy. Although the economic recovery has shown signs of fragility in OECD countries, global natural gas demand should continue to grow rapidly in the short-term, driven by consumption in developing countries, suggesting that the gas bubble will be reabsorbed faster than expected on the international markets.

Natural gas is being considered as an important transition fuel in an integrated national strategy to reduce emissions of greenhouse gases in the United States due to its lower carbon dioxide (CO 2 ) emission per unit of energy produced. However, the contribution of atmospheric methane (CH 4 ) from the production and handling of natural gas must also be considered. Radian Corporation has been working with the Gas Research Institute and the US Environmental Protection Agency to detail the sources of methane from the natural gas industry in the United States. All aspects of natural gas production, processing, transmission, storage and distribution are being examined. Preliminary results of preliminary testing for the below-ground gas distribution industry segment are presented. The emission rate (scf/hr) is the product of the leak rate per unit length of underground pipe and the total length of US distribution system pipelines. Preliminary estimates for the below-ground distribution segment are nearly 9 billion scf/yr. This total likely underestimates below-ground methane emissions for several reasons. These preliminary analyses suggest that significant uncertainty surround current methane emission estimates from below-ground distribution systems. Emission estimates from all segments of the US Natural Gas Industry, broken down by fugitive sources and non-fugitive sources, are also presented. The specific test methods being implemented to quantify emissions from each segment are described

The deregulation measures in the USA have led to increased regulation in the gas industry. There is no reason why these measures should be adopted in Europe. After a few remarks on the beginning of state regulation in the USA gas industry, the article goes on to consider the consequences of this policy (supply bottlenecks as a result of cost-oriented regulation of gas prices, surplus supply as a result of regulation-induced price increases).

The voice of Canada's oil and natural gas industry : oil and natural gas

International Nuclear Information System (INIS)

2001-04-01

The Canadian Association of Petroleum Producers (CAPP) represents 150 members of the oil and gas industry, which together are responsible for approximately 95 per cent of the oil and natural gas produced in Canada. The upstream sector comprises companies that explore for, develop and produce petroleum resources, while the downstream sector involves companies that refine and market the resources. CAPP works closely with governments of 11 of Canada's 13 provinces and territories and with public groups to represent upstream producers active across the country. The enhancement of the economic well-being and sustainability of the upstream petroleum industry is the mission of the CAPP. The main priorities of the CAPP are: Environment, Health and Safety Stewardship, reasonable and timely access to resources, competitiveness of the Canadian industry on a global basis, the secure and efficient access to markets, and open and constructive public, government and media affairs. Some of the issues dealt with by the CAPP are sour gas, flaring, venting and industry-landowner relations, improved safety performance, federal issues such as corporate taxes and environmental issues, Aboriginal and First Nations issues, transportation costs for natural gas on major pipelines, and oil and sands bitumen issues, to name a few. The board of the CAPP is made up of 32 members. The work is carried out by hundreds of volunteers from member companies who provide their time and expertise for various committees and working groups, as well as a staff of approximately 40 people to assist them. The members provide the entire funding for CAPP, which is located in Calgary, Alberta. The document concluded with a few facts concerning the petroleum industry in general. 12 figs

Decision year for gas industry. [Canada

Rowland, L; Rankin, A

1975-01-20

This year should be one of decision as far as the Canadian natural gas industry is concerned. There is urgent need to avoid the energy shortage now being experienced in the U.S., inasmuch as this year appears to mark the beginning of increasingly short supplies of gas in many parts of Canada. Increased gas plant construction and rising sulfur sales this year are 2 highlights of this annual natural gas report. A comprehensive listing of natural gas processing plants in Canada is given. Natural gas sales climbed by only 46 billion cu ft to an estimated 2,289 billion cu ft for a growth of 2% from 1973. The decline in exports will accelerate this year and as a result the overall gain this year is expected to be held to a modest 1% with an increase of 71 billion cu ft in the domestic sector and a drop of 58 billion cu ft in exports. Tabular data provide more complete details.

The natural gas industry and interest rates

In discussing the impact of Federal Energy Regulatory Commission (FERC) Order 636, the latest rule on the restructuring and deregulation of the US natural gas industry, the effect of interest rates on the success of the FERC policy is often overlooked. The thesis of this paper is that interest rates play an important role in integrating seasonal gas markets and in stimulating investment in storage infrastructure. We propose a model to analyse the equilibrium condition for an efficient gas market. Also analysed are the implications of pipeline rate design of FERC 636 for gas despatch decisions. (author)

On the Electrooxidation and Amperometric Detection of NO Gas at the Pt/Nafion® Electrode

Directory of Open Access Journals (Sweden)

Jin-Cherng Yang

2003-08-01

Full Text Available The electrochemical oxidation of nitric oxide (NO gas at the Pt/Nafion® electrode has been studied at a concentration of 500 ppm. The electrooxidation of NO taking place over a wide potential range can be described by a transcendental equation, from which the half-wave potential of the reaction can be determined. For NO oxidation with appreciable overpotentials but negligible mass-transfer effects, the Tafel kinetics applies. The obtained charge transfer coefficient (a and the exchange current density (io are 0.77 and 14 mA/cm2, respectively. An amperometric NO gas sensor based on the Pt/Nafion® electrode has been fabricated and tested over the NO concentration range from 0 to 500 ppm. The Pt/Nafion® electrode was used as an anode at a fixed potential, preferably 1.15 V (vs. Ag/AgCl/sat. KCl, which assures current limitation by diffusion only. The sensitivity of the electrochemical sensor was found to be 1.86 mA/ppm/cm2. The potential interference by other gases, such as nitrogen dioxide (NO2 and carbon monoxide (CO, was also studied in the range 0-500 ppm. Both sensitivity for NO and selectivity of NO over NO2/CO show significant enhancement upon using a cyclic voltammetric (CV activation, or cleaning procedure.

Albertans' views of the oil and gas industry: Angus Reid Group poll

International Nuclear Information System (INIS)

1999-01-01

The Angus Reid Group was commissioned to carry out research to determine and evaluate the image of the oil and gas industries in Alberta. The research was conducted using the Angus Reid Group's January Alberta omnibus study. Of 1200 telephone interviews conducted, 800 were completed by the general population of Alberta and 400 were completed by respondents who live in areas where there is a high level of activity by the oil and gas industries. All respondents were asked a series of questions on the image of the oil and gas industries in Alberta, while the oil and gas community respondents were asked a series of additional questions about their relationship to the oil and gas companies in their area. The 400 interviews with oil and gas communities were combined with the 800 general population interviews and the data were statistically weighed to ensure that the sample's age, gender and regional distribution reflects that of the actual adult populations of Alberta according to 1996 census data. The industries are generally seen as credible, and fifty-eight percent of Albertans see the oil and has industries as a good listener, while 38% do not agree. Fifty-three percent of Albertans see that the industries have become more responsible, and 7% disagree. Two thirds of Albertans see that the industries communicate well with the public, but one third does not. The two industries are seen as being on a par with other industries as far as social values are concerned. The main concern of Albertans about the two industries is that of the environment. A large group see that the industries are concerned about the environment, but they differ on whether actions are actually taken in support of the expressed concern. A majority see the relationship between the industries and themselves as good. tabs

Bright outlook for the gas industry

Energy Technology Data Exchange (ETDEWEB)

Gray, E

1969-06-23

The oil export picture may be cloudy, but the opposite is the case for gas, as consumption should boost gas sales some 60% over the next 4 yr. Beyond this, sales will be limited only by the growth of reserves. Indicative of the future is the projection of $1,000,000,000 in sales by 1975 with by-products holding up well despite weakening sulfur prices. Gas supplies in the U.S. are declining at a rapid rate and as a result that country's suppliers are looking to Alberta and the north to bridge the gap. While industry expects that tremendous gas reserves will be developed on the North Slope of Alaska, this does not pose as great a threat to Canadian producers as the North Slope oil reserves because of the relatively much higher cost of transporting natural gas, and the closer proximity to markets of Canadian gas. Whether ultimately transported in liquefied form by tanker, or by pipeline, gas from the North Slope will be high cost gas by the time it reaches U.S. Markets. Indicative of the U.S. hunger for more gas is the determined bid by Northern Natural Gas of Omaha, Neb. to obtain a major Canadian supply, which it has sought unsuccessfully to obtain for nearly 20 yr.

Natural gas industry competitiveness study

International Nuclear Information System (INIS)

1999-09-01

A national study on the competitiveness of the natural gas industry was undertaken by the BC Oil and Gas Commission in cooperation with, and with the encouragement of the Canadian Association of Petroleum Producers (CAPP). The objective of the study was to compare the cost competitiveness of natural gas exploration , production, gathering and processing in British Columbia to the costs of the same processes in Alberta. The study was carried out by building an 'expected case' for each gas producing area in British Columbia and Alberta by averaging past events in such specific areas as pool sizes, production profiles, loads, drilling success rates, gas compositions, land, drilling, exploration and production/gathering costs, third party production/gathering and processing fees and abandonment costs; by constructing a cash flow model for each case, calculating unit cost, and ranking cases. The report provides the details of the methodology, displays the results of the investigation in graphical form, comments on the results factoring in also labour costs and cost differences due to resource characteristics, identifies some trends such as an increase in the proportion of connections to smaller plants, and provides suggestions for improvements

The comments are inherent to the market liberalisation according to principles of graduality and of subsidiarity, the bipolar conception of this industrial sector with a subdivision of the activities in 'competitive' and in potentially m onopolistic , the free access to the networks, the un bundling of the integrated activities of the companies. Comments relevant to the definition of 'eligible customers' are of particular interest for the Italian gas industry as well as the operational conditions to be assured to the companies to which public service tasks are entrusted [it

The emerging role of natural gas on the African economy : the case study of the Nigerian gas industry

International Nuclear Information System (INIS)

Ndubuisi, E.N.; Amanetu, M.C.

2003-01-01

This paper presents a general overview of the African gas market, gas development, distribution, and utilization in Africa with particular emphasis on investment opportunities in Nigeria. Africa's non-renewable energy sources include fossil fuel such as coal, oil and natural gas. These fuels can be used to generate electricity. Their abundance is required for economic development and their efficient exploitation results in expansion of markets and industrialization, both of which are essential for Africa's social and economic progress. Natural gas is a premium fuel in the industrial, commercial and domestic sectors because of its unique characteristics. In Nigeria, the gas market is relatively untapped in the domestic sector, but much progress has been made in the past decade to develop and use natural gas as an energy feedstock for the cement and fertilizer industries. Some major gas transmission systems have been developed along with export oriented projects. 5 refs., 3 figs

Opportunities to reduce methane emissions in the natural gas industry

1995-12-31

The U.S. Environmental Protection Agency (EPA) and the Gas Research Institute (GRI) cofunded a project to quantify methane (CH{sub 4}) emissions from the U.S. natural gas industry. Methane, the major constituent of natural gas, is a potent greenhouse gas that is believed to increase the effect of global warming when released to the atmosphere. Reducing emissions from natural gas systems would lessen the greenhouse gas effect attributable to atmospheric CH{sub 4}. Further, mitigation methods to reduce emissions of natural gas, a marketable resource, could save money and increase energy efficiency. This presentation summarizes the major sources and quantity of methane being emitted to the atmosphere for all segments of the U.S. gas industry: production; processing; storage; transmission; and distribution. A description of how those emissions were determined is included here, as well as a discussion of which sources are potential candidates for reducing emissions. (author)

2018-02-01

We explored the adsorption of SO2, SOF2, and SO2F2 on Pt- or Au-doped MoS2 monolayer based on density functional theory. The adsorption energy, adsorption distance, charge transfer as well as density of states were discussed. SO2 and SOF2 exhibit strong chemical interactions with Pt-doped MoS2 based on large adsorption energy, charge transfer, and changes of electron orbitals in gas molecule. SO2 also shows obvious chemisorption on Au-doped MoS2 with apparent magnetism transfer from Au to gas molecules. The adsorption of SO2F2 on Pt-MoS2 and SOF2 on Au-MoS2 exhibits weaker chemical interactions and SO2F2 losses electrons when adsorbed on Pt-MoS2 which is different from other gas adsorption. The adsorption of SO2F2 on Au-MoS2 represents no obvious chemical interaction but physisorption. The gas-sensing properties are also evaluated based on DFT results. This work could provide prospects and application value for typical noble metal-doped MoS2 as gas-sensing materials.

Toward 2000 - potential changes facing the North American gas industry

International Nuclear Information System (INIS)

Baron, R.L.; Godec, M.L.

1997-01-01

Rapid changes in U.S. gas market developments and key factors that are likely to change future market outlook were reviewed. Currently, the biggest challenges facing the North American gas industry are deregulation in the electric power industry, technological advances, Canadian exports, environmental considerations, and new sources of natural gas from Mexico and Sable Island. Forces driving the natural gas demand include technological advances, growth in gas demand by electric utilities, and expansion of pipeline capacity. Uncertainties and threats to natural gas use include the rising cost of environmental compliance, the continued use of coal for power generation, and the Alliance Pipeline development. Technological advances such as 3-D seismic, horizontal drilling, improved completion techniques, longer-life bits, improved control systems, and reduced project cycle time, have been credited for producers now finding more gas reserves per well drilled than a decade ago. Present estimates of technically recoverable gas resources in North America run to about 2,500 trillion cubic feet

To begin with, it examines current conditions surrounding natural gas industry including domestic demand and supply conditions, world LNG market trend, structural changes of the industry in OECD countries, possibilities of introducing effective competition and assignment of existing import contracts. In doing so, we probe whether the direction of the natural gas industry restructuring is proper and suggest that the results be reflected when a more detailed restructuring implementation plan is formulated. Also, this report suggests possible schemes related to major institutional changes expected by the basic restructuring plan and the detailed restructuring implementation plan announced by the government. First, it presents several alternative ways to properly divide up the import/wholesales section of Korea Gas Corporation. Second, it examines critical issues such as the method of using gas supply facilities and gas balancing mechanism, and presents adoptable alternatives for each issue. These issues constitute the core of network and market operation rules which need to be in place when adopting an open access system, which in turn is a prerequisite for sales competition. Third, the report examines price systems, including gas commodity pricing and rate-making design for transportation service, by first anticipating the direction of changes in gas rate regulation. Specifically, it presents possible ways to design the service rate for each function of pipeline network and import terminals, and discusses controversial issues in determining total cost-of-service and allocating the cost-of-service to each functional service offered such as distance-related rates, interruptible service rate. Lastly, in relation to the opening of retail

Thin film thermocouples (TFTCs) can provide more precise in situ temperature measurement for aerospace propulsion systems without disturbance of gas flow and surface temperature distribution of the hot components. ITO/PtRh:PtRh TFTC with multilayer structure was deposited on alumina ceramic substrate by magnetron sputtering. After annealing, the TFTC was statically calibrated for multiple cycles with temperature up to 1000 °C. The TFTC with excellent stability and repeatability was realized for the negligible variation of EMF in different calibration cycles. It is believed that owing to oxygen diffusion barriers by the oxidation of top PtRh layer and Schottky barriers formed at the grain boundaries of ITO, the variation of the carrier concentration of ITO film is minimized. Meanwhile, the life time of TFTC is more than 30 h in harsh environment. This makes ITO/PtRh:PtRh TFTC a promising candidate for precise surface temperature measurement of hot components of aeroengines.

2015-05-01

Full Text Available Under pressure toward carbon emission reduction and air protection, China has accelerated energy restructuring by greatly improving the supply and consumption of natural gas in recent years. However, several issues with the sustainable development of the natural gas industry in China still need in-depth discussion. Therefore, based on the fundamental ideas of sustainable development, industrial development theories and features of the natural gas industry, a sustainable development theory is proposed in this thesis. The theory consists of five parts: resource, market, enterprise, technology and policy. The five parts, which unite for mutual connection and promotion, push the gas industry’s development forward together. Furthermore, based on the theoretical structure, the Natural Gas Industry Sustainability Index in China is established and evaluated via the Principal Component Analysis (PCA method. Finally, a conclusion is reached: that the sustainability of the natural gas industry in China kept rising from 2008 to 2013, mainly benefiting from increasing supply and demand, the enhancement of enterprise profits, technological innovation, policy support and the optimization and reformation of the gas market.

In a demonstration scale equipment for treatment of tritium in off-gas, Pt/SDBC as oxidation catalyst and Zeolite 13X as adsorbent was charged in the beds, respectively. It was confirmed from the performance test that decontamination factor of the equipment showed more than 100 under the flow rate of off-gas of 90 l/hr and at the temperature of 65 ∼ 80 .deg. C. A small scale CECE process has been developed combining LPCE catalytic column with SPE (solid polymer electrolyte) electrolysis. The catalytic column was a trickle-bed type packed with the mixture of 1 wt% Pt/SDBC catalyst and 4 mm Dixon wire-mesh ring. The experimental results of the CECE process proved that the decontamination factor of 13 ∼ 20 under the operating conditions of the water of the 4 l/day and the effluent hydrogen gas of 16.2 mol/h. A design code of CECE process also developed which will be applied the tritium industry. An experimental method for the reduction of tritiated organic waste by using catalytic oxidation was tested in a heated catalytic reactor of 0.5 wt% Pd/Al 2 O 3 . The simulated organic liquid was converted to water over 99%. A gas chromatographic column material was developed for the separation of mixed hydrogen isotopes. 17 wt% Pd-Pt on alumina showed 90% separation efficiency at 77 % yield for the separation of 29.2 % D 2 -H 2 gas mixture

French gas industry in transition: breach in the public service model

International Nuclear Information System (INIS)

Finon, D.

2001-08-01

France is generally viewed as the European country that most vigorously resists the pressure to liberalize its national gas markets. The moderate reform which has resulted from the transcription of the European gas directive was voted in 2002 after much delay. The main reason is the robustness of the French public service-model which has shaped the gas industry organisation in the same way as most of the network industries. To explain the institutional stability of the French gas industry, this document analyses its institutional trajectory shaped by the public service model and its strong institutional path dependency, marked by the resistance to change. The central hypothesis of the analysis is that, as long as this model demonstrates economic and social efficiency in the development of gas supply in relation to public services obligation and in the control of the import dependence risk in the gas sector, no reform can be brought about by endogenous factors. The analysis of the French gas industry transition consists of four sections. After a survey of its historical development, the author presents its organisation and regulation under the public service model and its performances in terms of social and economic efficiency. In the third section, the minimalist reform for transcribing the European Directive in the French law is presented, in order to identify its potential effects in terms of competition development and public service erosion. Finally, in the fourth section, the industrial policy option to preserve the existence of a French mono-energy company and its consequences in terms of strategic adaptation are discussed. (A.L.B.)

To keep up with the increasing amount of natural gas that will be required by the market and with the decreasing quality of the gas at the well-head, the gas processing industry must look to new technologies to stay competitive. The Gas Research Institute (GR); is managing a research, development, design and deployment program that is projected to save the industry US dollar 230 million/year in operating and capital costs from gas processing related activities in NGL extraction and recovery, dehydration, acid gas removal/sulfur recovery, and nitrogen rejection. Three technologies are addressed here. Multivariable Control (MVC) technology for predictive process control and optimization is installed or in design at fourteen facilities treating a combined total of over 30x10 9 normal cubic meter per year (BN m 3 /y) [1.1x10 12 standard cubic feet per year (Tcf/y)]. Simple pay backs are typically under 6 months. A new acid gas removal process based on n-formyl morpholine (NFM) is being field tested that offers 40-50% savings in operating costs and 15-30% savings in capital costs relative to a commercially available physical solvent. The GRI-MemCalc TM Computer Program for Membrane Separations and the GRI-Scavenger CalcBase TM Computer Program for Scavenging Technologies are screening tools that engineers can use to determine the best practice for treating their gas.

Cyclic voltammetry is a fundamental experimental method for characterizing electrochemical surfaces. Despite its wide use, a way to quantitatively and directly relate cyclic voltammetry to ab initio calculations has been lacking. We derive the cyclic voltammogram for H on Pt(111) and Pt(100), bas...... solely on density functional theory calculations and standard molecular tables. By relating the gas phase adsorption energy to the electrochemical electrode potential, we provide a direct link between surface science and electrochemistry....

International Nuclear Information System (INIS)

Li, Mei; Li, Changrong; Wang, Fuming; Zhang, Weijing

2007-01-01

In order to analyze the Pt/GaAs interfacial reaction sequence, the As-Pt binary system was thermodynamically assessed. A consistent thermodynamic data set for the As-Pt binary system have been obtained by means of calculation of phase diagrams (CALPHAD) technology. The intermetallic compound, As 2 Pt, was treated as stoichiometric compound. The gas phase was treated as an ideal mixture. Using the present thermodynamic data set for the As-Pt system and the literatures reported ones for the Ga-Pt and As-Ga systems, the isothermal sections of the As-Ga-Pt system at different temperatures 873 and 298 K were constructed by extending the related binaries. The calculated phase diagrams reproduce the experimental results well. Based on the present optimized data and the phase equilibrium calculation, the interfacial reactions of (bulk Pt)/GaAs and (thin-film Pt)/GaAs couples were analyzed and the phase formation sequences were predicted. The calculation results agree well with the reported experiments

Privatisation and regulation - the effect on the U.K. gas industry

International Nuclear Information System (INIS)

Price, C.

1991-01-01

The U.K. gas industry is a monopolist, privatised in 1986 and subject to partial regulation and general monopoly policy. From April 1992 a new regulatory regime will be applied. This paper explores the impact of privatisation and partial regulation in the gas industry during the first quinquennium and illustrates the issues for regulation and pricing where costs are common to regulated and unregulated sectors. Attributable costs of gas supply are derived and a 'marginal cost' based tariff suggested. This is used as a basis for examining the industry's pricing policy in its several markets, and to analyse its response to privatisation and the regulation it has experienced. (Author)

Is further deregulation of the natural gas industry beneficial : discussion paper

Hoey, P.J. [Anbrer Consulting, Ottawa, ON (Canada)

2004-11-01

Energy market liberalization is a world trend that has prompted the deregulation of natural gas and electricity over the past twenty years in North America. The Ontario Energy Board and the National Energy Board are conducting public hearings on natural gas regulation in response to the request by Canadian energy industries for better regulatory streamlining. The following 5 issues regarding natural gas regulation in Canada have been examined: (1) system gas in a regulated market, (2) natural gas infrastructure investments and capital renewal, (3) improving efficiency in gas regulation, (4) expectations of performance-based regulation (PBR) in the natural gas industry, and (5) the debate whether further deregulation of the natural gas industry is beneficial. This paper examines if a competitive market exists in natural gas distribution and discusses the opportunities for further deregulation of the distribution and storage aspects of the industry. It was noted that the regulatory regime in Ontario will depend on how the Ontario Energy Board deals with issues regarding natural gas storage services. This paper also examines if new storage facilities can charge cost-based or market-based prices as well as the appropriate rate of return on capital to be used to determine those rates. It also examines what the requirement for non-discriminatory access to and from new storage facilities to the Dawn Hub and access to transmission capacity on Union Gas's Dawn to Trafalger pipeline system. Alternative fuels, franchises, bypasses, gated communities, distributed generation, market power and policy issues are the main factors that are considered in assessing the competition in natural gas distribution. It was concluded that further deregulation of the natural gas distribution system in Ontario is not warranted since there is not much possibility in developing a competitive market for distribution services in the short-term.

Substation interference on gas entrance of industrial plants

Energy Technology Data Exchange (ETDEWEB)

Freire, Paulo Edmundo; Giacommelo, Claudinei [PAIOL Engenharia, Paulinia, SP (Brazil)

2009-12-19

Industrial plants often have medium or high voltage electrical power entrance and also gas feeders. Often the main substation is located near the gas entrance, in the utilities area. When the occurrence of a phase to ground short-circuit in the substation, the pipeline and gas entrance that serves the plant may be exposed to high voltage soil potential, of the order of a few kilovolts, due to resistive coupling with the substation ground mesh. The consequences of this situation are reflected in various risks, with emphasis on: damage to the protective coating of the duct, due to the increased soil potential, in excess of its dielectric supportability (typically on the order of 5 kV); spread of potentially hazardous to duct exposed parts (valves, measuring place etc.); and damage to cathodic protection system components, as rectifier and insulating joins at gas entrance. This paper presents the investigations conducted in a factory that has a 69 kV main substation very close to the gas entrance, the order of a few meters away. The substation phase to ground short-circuit current is 7 kA, what causes a 9 kV soil potential near the gas pipe. It is presented the methodology for modeling the various elements involved in this process, the results of simulations made, arrangements been taken to reduce soil potential next to the duct to levels below 5 kV, and the measures for people and insulating joins protection. It is important to note that such problems usually will be solved with measures involving the entire grounding system of the industrial complex and also close to the duct (outside the industrial plant). The gas distribution companies should require from customers where this situation occurs, to ensure safety for people who have access to elements of its network, and for the integrity of their own ducts and cathodic protection components. The computer simulations developed for this work were made with the software Auto Grid, developed by the Canadian company Safe

A review of the state of the Canadian oil and gas industry for 1997 was presented. In 1997, capital investment levels were at $19 billion with oil, gas and gas by-products production valued at $31 billion. Exports were strong and set to grow further. As far as the Yukon is concerned, the availability of increased incentives and the announcement of a common royalty regime for the Territory have helped to increase interest by outside capital. Ongoing efforts are being made to include First Nations communities in the public consultation processes, and to ensure significant benefits to First Nation people from any development. The industry's initiatives and approaches to exploration, development and production were outlined. Environmental initiatives to protect the wilderness, and the existing ecosystem were described with examples from Alberta (Special Places 2000) and from British Columbia (BC Northern Rockies (Muskwa-Kechika; marine protected areas). 1 fig

Technical potential for developing natural gas use in the Brazilian red ceramic industry

International Nuclear Information System (INIS)

Schwob, Marcelo Rousseau Valenca; Henriques, Mauricio Jr.; Szklo, Alexandre

2009-01-01

The red ceramic industry in Brazil, consisting of over 7000 companies, requires large amounts of thermal energy, currently being met mainly by native fuelwood, which causes serious deforestation and soil erosion problems. The use of firewood does not allow achieving good energy performance in industrial ceramic kilns, causing high energy losses, low productivity and low quality products (bricks and roof tiles). Thus, to implement higher added value products, besides mitigate environmental problems caused by deforestation, the use of natural gas by the sector seems to be a promising alternative. Brazil's natural gas market has grown at a fast pace in recent years. Its share in the country's primary energy consumption increased from 3.7% to 9.3% between 1998 and 2007, compared to almost 21% in the world. The development of the Brazilian natural gas industry was grounded on stepping up supplies through integration with Bolivia from where natural gas is imported, together with fiscal incentives for promoting the demand. This paper estimates that the natural gas market that could be developed in the Brazilian red ceramic industry corresponds to less than 5% of the total industrial natural gas consumption, meaning that a major technological transformation of the country's red ceramic industry will not severely affect the natural gas market equilibrium, contributing to reduce the country's high rates of deforestation.

Malaysia's petroleum industry is looking forward to an expansionary period until the end of the century, with the role of gas being greatly enhanced. The state oil firm Petronas sees increasing oil and gas reserves, making fuller use of abundant gas reserves, an exploration thrust into deepwater areas and the intensification of environmental protection as some of the points of emphasis in its current programme. The state firm president Tan Sri Datuk Azizan Zainul Abidin says that in the past few years a national economic growth rate of 8 percent has resulted in rising energy demand. Economic growth is projected to continue, so that an increase in power demand can be expected for the next few years. 'Fortunately, we are experiencing the same bullish trend in oil exploration and development,' he says. (author)

In this paper we report a technique that can directly fabricate L1 0 phase FePt nanoparticles. FePt nanoparticles were generated through gas-phase aggregation using a magnetron-sputtering-based nanocluster source. Following the source chamber, an online halogen-lamp heater was used for the L1 0 phase formation during the particles' flight in vacuum. Transmission electron microscopy and vibrating-sample magnetometer data verified the successful fabrication of the L1 0 phase FePt nanoparticles. The coercivity value at 300 K is 1100 Oe for the nanoparticles with online heating. Neon carrier gas was applied to manipulate FePt nanoparticle size and to enhance particle size uniformity. The size dependence of nanoparticle ordering was investigated

2016-03-01

The soaring increase of flue gas emission had caused global warming, environmental pollution as well as climate change. Widespread concern on reduction of flue gas released from industrial plants had considered the microalgae as excellent biological materials for recycling the carbon dioxide directly emitted from exhaust industries. Microalgae also have the potential to be the valuable feedback for renewable energy production due to their high growth rate and abilities to sequester inorganic carbon through photosynthetic process. In this review article, we will illustrate important relative mechanisms in the metabolic processes of biofixation by microalgae and their recent experimental researches and advances of sequestration of carbon dioxide by microalgae on actual industrial and stimulate flue gases, novel photobioreactor cultivation systems as well as the perspectives and limitations of microalgal cultivation in further development.

Global methane emissions from the fossil fuel industries have been poorly quantified and, in many cases, emissions are not well-known even at the country level. Historically, methane emissions from the U.S. gas industry have been based on sparse data, incorrect assumptions, or both. As a result, the estimate of the contribution these emissions make to the global methane inventory could be inaccurate. For this reason the assertion that global warming could be reduced by replacing coal and oil fuels with natural gas could not be defended. A recently completed, multi year study conducted by the U.S. Environmental Protection Agency's Office of Research and Development and the Gas Research Institute, had the objective of determining methane emissions from the U.S. gas industry with an accuracy of ± 0.5% of production. The study concluded that, in the 1992 base year, methane emissions from the industry were 314 ± 105 Bscf or 6.04 ± 2.01 Tg (all conversions to international units are made at 15.56 o C and 101.325 kPa).

This study aims to investigate the real possibilities for the natural gas industry to become a global energy industry. So, it is necessary to define what global energy industry really means. In order to do a comparative analysis between the oil and natural gas industries, it is necessary to define three distinct stages of the evolution of an energy industry, namely internationalization, mundialization and globalization. This study analyzes the evolution of the oil industry trying to identify the main aspects that promoted changes and transformed the oil business into a global industry. Then, the evolution of the natural gas industry is analyzed, looking for similarities between the structural changes in both industries, and trying to determine what is the current stage of the natural gas industry. Despite the increase in the natural gas international trade and the prospects of growth of natural gas demand, there are still some challenges for this industry to effectively become global. Some of the challenges are the need of investments in production infrastructure, transportation and distribution sectors, the access to the main reserves, the uncertainty related to the demand evolution and the possible creation of a natural gas producers cartel, like the Organization of the Petroleum Exporting Countries (OPEC).

In the nineties, natural gas was the fastest growing energy source in the world energy mix. However, recent developments on the energy scene, particularly in terms of prices, have strongly impacted the growth of the various energies to the detriment of natural gas. Beyond this inter-energy competition, which could intensify, medium-term prospects for the gas industry evolve in an environment beset with uncertainties. (author)

Detecting decompositions of sulfur hexafluoride using reduced graphene oxide decorated with Pt nanoparticles

Science.gov (United States)

Chen, Dachang; Tang, Ju; Zhang, Xiaoxing; Fang, Jiani; Li, Yi; Zhuo, Ran

2018-05-01

The resistance-typed gas sensing material of Pt nanoparticles (PtNPs) decorated reduced graphene oxide (RGO) synthesized by one-step chemical reduction for the detection of four types of SF6 decompositions was explored. The PtNPs disperse uniformly on RGO with particle size near 2–4 nm and a small number of particles are larger than 10 nm. Gas sensing tests suggest that the introduction of PtNPs increases the response to SO2, SOF2 and H2S compared to pure RGO and PtNPs-RGO experiences resistance reducing in SO2 and SOF2 while presenting the opposite case in H2S. Elevating the temperature enhances the recovery properties to SO2 and H2S but lowers the sensitivity. The sensing mechanism for Pt-RGO in low oxygen and water environment depends mainly on the charge transfer between gas and adsorbent and the solvent on material surface. The work provides experimental investigation of Pt-RGO to detect SF6 decompositions.

Cowie, Michael; Mously, Khalid; Fageeha, Osama; Nassar, Rafat

2008-01-01

It has been established that Naturally Occurring Radioactive Materials (NORM) may accumulate at various locations along the oil/gas production process. Components such as wellheads, separation vessels, pumps, and other processing equipment can become NORM contaminated, and NORM can accumulate in the form of sludge, scale, scrapings and other waste media. This can create a potential radiation hazard to workers, general public and the environment if certain controls are not established. Saudi Aramco has developed NORM management guidelines and is implementing a comprehensive strategy to address all aspects of NORM management which aim towards enhancing: NORM monitoring; Control of NORM contaminated equipment; Control over NORM waste handling and disposal; Workers protection, awareness, and training. The benefits of shared knowledge, best practice and, experience across the oil and gas industry are seen as key to the establishment of common guidance. This paper outlines Saudi Aramco's experience in the development of a NORM management strategy and its goals of establishing common guidance throughout the oil and gas industry. (author)

Atmospheric emissions from the upstream oil and gas industry

The results are presented of a study set up to determine the nature and levels of atmospheric emissions resulting from United Kingdom oil and gas exploration and production activities. The study was commissioned by the UK Offshore Operators Association. Emissions by the upstream oil and gas industry of common pollutants, such as carbon monoxide, sulphur dioxide and nitrous oxide, and ozone depletion chemicals were shown in each case to be less than 1% of total UK emissions. Greenhouse gas emissions in the industry arise mainly from production operations with a small but significant contribution from onshore activities. Carbon dioxide is the major component followed in descending order by nitrogen oxides, methane and volatile organic compounds. In 1991, these emissions formed 3.2%, 4.6%, 2.9% and 2.8% of the UK totals respectively; overall this represented only about 3% of UK global warming emissions. The evidence of this study illustrates that the industry, which produces 67% of the UK's primary energy, is successfully managing its operations in an environmentally responsible way.

Prospects of and challenges to natural gas industry development in China

Full Text Available An unprecedented breakthrough has been made over the past decades in natural gas industry, which helps improve energy mix and promote the low-carbon economy in China. With such abundant hydrocarbon resources, China owns two intensive oil and gas producing blocks in the Ordos Basin and Xinjiang province and two other concentrated gas producing blocks in Sichuan and Western South Sea. In addition, arterial gas lines have been connected as a gas grid all over China and natural gas market has become more and more mature and expanded. Thus, a natural gas industry system has come into being. However, with natural gas unevenly scattering all across China, the remnant resources mainly are distributed in the stratigraphic strata, deep strata in superimposed basins or in mature exploration zones, foreland basin thrust belts, marine gas fields, and so on. In reality, the future gas exploration should focus on such domains as the weathered crust karst reservoirs or carbonate and stratigraphic traps, deep clastic gas layers, and unconventional oil and gas plays. Achievements have been made in marine shale gas exploration, CBM gas steady development, and other unconventional natural gas resources. From the perspective of exploration potential, more giant oil and gas fields will be possibly discovered in deep strata or deep sea water, and stratigraphic hydrocarbon reservoirs and tight oil and gas reservoirs will also be the exploration focus. With the increase of exploration depth and degree, the overall oil and gas exploration cost will be significantly rising in general. New discoveries or reserves increase in natural gas exploration will highly depend upon research theory and technology progress, and such development technologies as 3D seismic survey, horizontal drilling and fracturing treatment will be more highlighted. Through enhancing the cost in natural gas exploration and development and strengthening the research of core technologies, natural gas

Gas has emerged as one of the most desirable fuels for a wide range of applications that previously have been supplied by oil, coal, or nuclear energy. Compared to these, it is environmentally clean and burns at efficiencies far in excess of competitive fuels. The penetration of gas as the fuel of choice in most parts of the world is still modest. This is particularly true in newly-developed countries that are engaged in rapid industrialization and where rates of growth in the gross domestic products are two or three times greater than in the Organization for Economic Cooperation and Development (OECD) countries. I will not attempt here to survey the world gas scene comprehensively. I will, however, attempt to focus on some aspects of the industry that could be the trigger points for global development. These triggers are occurring all along the gas chain, by which I mean the entire process of bringing gas to the customer from discovery through delivery. The chain includes exploration and production, power generation, transmission, and distribution. I describe an industry that is on the verge of truly global status, which is fast overcoming the remaining obstacles to transnational trade, and which has unusually exciting long-term prospects. It does have a good way to go before it achieves the maturity of the international oil industry, but in the last few years there has been a tremendous growth of confidence among both investors and users. The global gas industry is certainly developing at a fast pace, and the world can only benefit from the wider availability of this clean, economic, and efficient hydrocarbon

Human and Organisational Safety Barriers in the Oil & Gas Industry

International Nuclear Information System (INIS)

Nystad, E.; Szőke, I.

2016-01-01

The oil & gas industry is a safety-critical industry where errors or accidents may potentially have severe consequences. Offshore oil & gas installations are complex technical systems constructed to pump hydrocarbons from below the seabed, process them and pipe them to onshore refineries. Hydrocarbon leaks may lead to major accidents or have negative environmental impacts. The industry must therefore have a strong focus on safety. Safety barriers are devices put into place to prevent or reduce the effects of unwanted incidents. Technical barriers are one type of safety barrier, e.g., blow-out preventers to prevent uncontrolled release of hydrocarbons from a well. Human operators may also have an important function in maintaining safety. These human operators are part of a larger organisation consisting of different roles and responsibilities and with different mechanisms for ensuring safety. This paper will present two research projects from the Norwegian oil & gas industry that look at the role of humans and organisations as safety barriers. The first project used questionnaire data to investigate the use of mindful safety practices (safety-promoting work practices intended to prevent or interrupt unwanted events) and what contextual factors may affect employees’ willingness to use these safety practices. Among the findings was that employees’ willingness to use mindful safety practices was affected more by factors on a group level than factors at an individual or organisational level, and that the factors may differ depending on what is the object of a practice—the employee or other persons. It was also suggested that employees’ willingness to use mindful safety practices could be an indicator used in the assessment of the safety level on oil & gas installations. The second project is related to organisational safety barriers against major accidents. This project was based on a review of recent incidents in the Norwegian oil & gas industry, as well as

The utility industry team concluded that the plant design should be considered a viable application of an advanced nuclear concept and deserves continuing development. Specific comments and recommendations are provided as a contribution toward improving a very promising plant design. 2 refs

The Ralph review - tax reform and the Australian gas industry

International Nuclear Information System (INIS)

Horden, P.; Kellock, I.

1999-01-01

The impact of the Federal Government's tax reform package on the Australian gas industry will be generally negative, particularly in terms of infrastructure investment, according to Pricewaterhouse Coopers' Peter Hordern and Ian Kellock. This article examines the critical aspects of the package. Overall, the impact of the tax reform package (consisting of the Ralph committee's report and the Government's initial response) on the Australian gas industry would appear to be negative. The removal of accelerated depreciation and the potential for severe limitations on leasing arrangements is particularly bad news. While the proposed reduction in the company tax rate may appear positive, this is unlikely to provide significant benefit to the industry. The reality is existing gas infrastructure investors are generally in tax losses and will derive no immediate benefit from the rate change. For new investors, the reduction in rate will not offset the loss of accelerated depreciation deductions

2007-01-01

During the 1990's, natural gas was the energy source with the fastest rate of growth in the world energy balance. Nevertheless, recent evolutions of the energy context, in particular in terms of prices, have had a rather strong impact on the progress of the different energy sources penalizing gas a little. Beyond this competition between energies, which may increase, the medium-term perspectives of natural gas development is in keeping with an environment full of uncertainties. This article presents: the world supply and demand prospects for 2010-2015 (impact of high gas prices on other energy sources, occurrence of production constraints, political decisions of producing countries and world gas industry balance), trends on main markets (North America, Europe, Asia-Oceania), and international trade.

Due to sustained competition between energy sources and an economic and geopolitical climate that is still unstable, gas growth has slowed. The year 2013 looks very mixed for the gas industry, particularly on the upstream side. Constraints on the supply of gas and the increased dependence on imports in consumer markets increase the vulnerability of the gas markets to the vagaries of geopolitical risks and result in tensions on the international market. In an environment full of uncertainties about future prices and contractual terms, investors are slow to initiate the projects necessary for a global gas balance in this decade. (author)

Scott, I.F.H.

1997-01-01

Abandonment issues in the oil and gas industry, such as well sites, batteries, gas plants, compressor stations, and pipelines, were discussed. Responsibilities of the Canadian Association of Petroleum Producers (CAPP) for informing the Canadian public about energy and environmental issues on behalf of the upstream petroleum industry were reviewed. Industry regulators and those who have jurisdiction over the abandonment of facilities were identified. In Alberta, the main agencies are the Alberta Energy and Utilities Board, Alberta Environmental Protection, and Alberta Food and Rural Development in addition to the National Energy Board and Indian Oil and Gas Canada. At the end of 1995, 160,000 wells had been drilled in Alberta of which 60,000 are still active, 35,000 are suspended and 70,000 wells have been abandoned. The industry-financed Orphan Well Program was established to provide funds for facility abandonment, decontamination and surface reclamation costs associated with orphaned facilities. CAPP agrees that operators of oil and gas facilities must be held responsible and accountable for the abandonment of their facilities. CAPP is looking for support from government to ensure that enforcement actions limit the number of orphan facilities. tabs., figs

Mishkin, M.T.; Adelman, D.I.

1994-01-01

On December 23, 1993, the Federal Energy Regulatory Commission (FERC) issued Order 563, a Final Rule adopting the agreements of informal industry-wide working groups to standardize information relating to pipeline capacity release programs mandated under Order 636. Order 563 is noteworthy for its reliance upon the industry to develop consensus standards for Commission adoption. The industry's success in reaching agreements on key communication standards issues spawned recommendations from the working groups to continue the development and maintenance of industry-wide standards through a permanent Gas Industry Standards Board (GISB). This article examines legal issues bearing on GISB's potential role in the regulatory process. Specifically, this article addresses constitutional and statutory considerations relating to the FERC's authority to delegate certain responsibilities to a voluntary, industry sponsored and supported private body such as that taking shape within the gas industry.

Three examples of natural gas distribution companies involved in merger activity illustrate how the distribution as well as the transmission side of the industry may be attractive to potential acquiring companies seeking diversification. Although the mergers are a new phenonmenon, the acquiring firms are attracted by the overlapping service areas and the operating efficiency of the regulated distributors. They also see a possible outlet for surplus natural gas. 1 table.

The development of the UK landfill gas industry: an overview

1996-01-01

The UK's landfill gas research started in 1978 and led to the first commercial scheme in 1981 where the gas was used to fire a brick kiln. Electricity generation followed in 1984. Although by 1990 there were nearly two dozen operational schemes, the real impetus to usage was given by the NFFO. Here all electricity generated could be sold irrespective of the demand. Although the Department of Energy - and latterly the Department of Trade and Industry - invested substantial monies in the early research and development, the greatest factor in the success of the industry has been willingness to take its own risks. The industry must now learn to live with lower revenues and heightened environmental requirements. (Author)

Upstream oil and gas industry options paper : report of the upstream oil and gas working group of the Industry Issues Table to the National Climate Change Secretariat

1999-09-01

The Canadian Association of Petroleum Producers (CAPP) has coordinated the efforts of the upstream oil and natural gas industry to draft a foundation paper to provide data on industry greenhouse gas (GHG) emissions and actions. This paper is a technical piece targeted at government officials and stakeholders involved in the National Climate Change Secretariat process. The paper also outlines the context for considering policies aimed at reducing oil and gas industry emissions on climate change. The 6 key messages that CAPP wanted to emphasize in this paper were: (1) Canada's situation is very different from that of the U.S. and most other industrial countries, (2) GHG emissions are primarily an end-use consumption issue, (3) the climate change issue and the Kyoto Protocol present a major uncertainty that could undermine Canadian oil and natural gas development opportunities, (4) Canada should not be penalised by its growth of oil and natural gas resources, (5) the ability to reduce emissions by changing production technology is limited because large reductions in Canadian upstream emissions would only mean a shift of production to other countries which would not help to reduce global emissions, and (6) Canada should focus on promoting cost-effective action, research and development and international flexibility, and ensure that recognition is given to those companies that reduce emissions. tabs., figs

2004-01-01

Growing industrialization, if not mere population growth, on the face of the Earth will induce organizations and nations world wide to reconsider the variety, priority, and efficiency of their energy sources. Natural gas has become the world's premier energy source because it is efficient, adaptable, and environmentally safer than other fossil fuels. The vehicular sector is a growing and major fuel consuming sector in any economy. Technological advancements and the flow of funds in that industry have allowed nations to target that sector as a priority in a plan to achieve maximum adaptation to natural gas consumption. The use of compressed natural gas vehicles dates back to the 1930 s in Italy. The late 70 however witnessed the launch of and commitment to a growing and developing industry.

Energy efficiency and fuel switching in Canadian industry under greenhouse gas regulation

International Nuclear Information System (INIS)

Margolick, M.

1992-01-01

The application of financial instruments to greenhouse gas control, particularly a greenhouse gas tax, is discussed. As of June 1991, Finland, the Netherlands, Sweden and Norway have imposed taxes on greenhouse gas emissions, while taxes are imminent in Denmark and Germany. A study has been carried out to model the effects of such taxes on greenhouse gas emissions in Canada, using the Intra-Sectoral Technology Use Model (ISTUM) and an end-use energy demand computer model. Only carbon dioxide and methane were considered. The limitations of the ISTUM model are discussed. Industry results are presented by sector, including an overview of greenhouse gas-producing processes, emission reduction measures possible, energy and greenhouse emissions, and results of taxes at varying levels. Different basic physical and chemical processes among industries would cause widely varying responses to a greenhouse gas tax. Issues which bear directly on greenhouse gas emissions include the burning of biomass fuels in the pulp and paper industry, strategic choices between existing and new technologies in the iron and steel sector, the possibility of a nearly greenhouse gas-free aluminum smelting sector, and the advent of reformulated gasoline requirements and declining crude oil quantity in the petroleum refining sector. 15 refs., 6 figs

The oil and gas industry and the Canadian economy: a backgrounder

International Nuclear Information System (INIS)

Curran, R.

2000-02-01

The impact of the oil and natural gas industry on the Canadian economy is explained in terms of employment, balance of trade, products, government revenues, international technology trade and industry support to the community. It is reported that the industry employs almost one half million people in Canada; is the second largest contributor to Canada's balance of trade; generate billions of dollars for the economy and pays hundreds of millions of dollars in taxes and its employees contribute millions of dollars and thousands of hours of time to charitable and community organizations. The industry is also one of the major contributors to Canada's technology export through its leadership in high technology exploration methods, cold climate and offshore operations, enhanced recovery technologies, producing and processing heavy oil; mining and upgrading oil sands bitumen, oil-well firefighting techniques and environmental protection technologies, among others. Citing Canada's cold climate and energy-intensive industries, hence the need for large quantities of energy, the booklet offers a rationale for the industry's need to continue to be profitable in order to develop new sources of oil and gas production and invest in energy-efficient technologies. Assuming continued profitability, combined with more efficient use of oil and gas, the Foundation remains confident that the industry will provide energy security and export revenues for the benefit of all Canadians. 12 refs., photos

Characterization of Industrial Pt-Sn/Al2O3 Catalyst and Transient Product Formations during Propane Dehydrogenation

Directory of Open Access Journals (Sweden)

Kah Sing Ho

2013-06-01

Full Text Available The major problem plaguing propane dehydrogenation process is the coke formation on the Pt-Sn/Al2O3 catalyst which leads to catalyst deactivation. Due to information paucity, the physicochemical characteristics of the commercially obtained regenerated Pt-Sn/Al2O3 catalyst (operated in moving bed reactor and coke formation at different temperatures of reaction were discussed. The physicochemical characterization of regenerated catalyst gave a BET surface area of 104.0 m2/g with graphitic carbon content of 8.0% indicative of incomplete carbon gasification during the industrial propylene production. Effect of temperatures on coke formation was identified by studying the product yield via temperature-programmed reaction carried out at 500oC, 600oC and 700oC. It was found that ethylene was precursor to carbon laydown while propylene tends to crack into methane. Post reaction, the spent catalyst possessed relatively lower surface area and pore radius whilst exhibited higher carbon content (31.80% at 700oC compared to the regenerated catalyst. Significantly, current studies also found that higher reaction temperatures favoured the coke formation. Consequently, the propylene yield has decreased with reaction temperature. © 2013 BCREC UNDIP.

Botezatu, E.; Grecea, C.

2006-01-01

The objective of this study was to assess the radiological impact on the environment and population of the oil/gas industry that is non-nuclear industry but uses and can produce materials, with an enhanced content of naturally occurring radionuclides. The natural radioactivity levels in the oil field environmental media, which could represent a risk for the people living in the areas influenced by this non-nuclear industry, do not indicate an increase in the natural radiation background. From a radiological point of view, the situation does not pose any immediate concern. Some places however need further investigations, with special emphasis on the control of 226 Ra releases to prevent from polluting the environment with this radionuclide. The growing concern amongst the population about the quality of their environment increases the significance of impact assessment of radioactive releases into the environment even if natural radionuclides occur.

Liberalization and enlargement: effects of the industrial organisation of natural gas markets in Eastern Europe

International Nuclear Information System (INIS)

Pirovska, M.

2005-01-01

After half a century of political division within the European continent, and of State control over national energy industries, a new industrial and political organisation model aiming at creating a single natural gas market tends to emerge currently within the enlarged European Union. Yet new member countries are former centrally planned, socialist economies, with very different industrial structures for natural gas. However, those countries should adjust to the institutional framework applicable in the European Union, including bringing their gas industries into compliance with the liberalization process that old member countries initiated years ago. In that unprecedented context, one basic issue is whether the gas industry liberalization, in the framework of the enlargement, will have expected results in terms of competition, efficiency and profits for Eastern countries, whether new members or candidates for membership. The objective of the research work behind this article was to analyse the effects of that complex trend on the industrial organisation of gas markets in eastern Europe. (author)

Natural gas demand is forecast to rise dramatically in both Japan and Europe in the next two decades. Between the Japanese gas market and that of West European countries, however, there are considerable differences as well as some similarities. This study looks at demand and supply of natural gas, the history and structure of the industries, and the regulatory regimes, in both Japan and West European countries. It concentrates specifically on the latest moves towards liberalization of gas markets. Finally it considers possible implications of the European experience for the future of the industry in Japan, where not only is the government about to introduce a more competitive environment, but construction of a national transmission pipeline is under active consideration.

Yang, Zhengbao; Zu, Jean

2016-01-01

Highlights: • Systematic analysis of PMN-PT and PZN-PT single crystals for energy harvesters. • Performance analysis and comparison under various conditions. • Discussion of the effect of the SSHI technique on single crystal energy harvesters. • Efficiency analysis in both on-resonance and off-resonance conditions. - Abstract: Vibration energy harvesting has a great potential to achieve self-powered operations for wireless sensors, wearable devices and medical electronics, and thus has attracted much attention in academia and industry. The majority of research into this subject has focused on the piezoelectric effect of synthetic materials, especially the perovskite PZT ceramics. Recently the new-generation piezoelectric materials PMN-PT and PZN-PT single crystals have gained significant interest because of their outstanding piezoelectric properties. They can be used to replace the widely-adopted PZT ceramics for improving energy harvesters’ performance substantially. However, there is little research on comparing PMN-PT and PZN-PT energy harvesters against PZT harvesters. In this paper, we present a systematic comparison between vibration energy harvesters using the PMN-PT, PZN-PT single crystals and those using the PZT ceramics. Key properties of the three materials are summarized and compared. The performance of the PMN-PT and PZN-PT energy harvesters is characterized under different conditions (beam length, resistance, frequency, excitation strength, and backward coupling effect), and is quantitatively compared with the PZT counterpart. Furthermore, the effect of the synchronized switch harvesting on inductor (SSHI) circuit on the three harvesters is discussed. The experimental results indicate that energy harvesters using the PMN-PT and PZN-PT single crystals can significantly outperform those using the PZT ceramics. This study provides a strong base for future research on high-performance energy harvesters using the new PMN-PT and PZN-PT single

It is presented two negotiation models (Bilateral and Poolco) that are being used by natural gas industry at the present time. The main differences are characterized between these models. Basically, these differences can be found in the nature of the transactions and in the way as they are coordinated by the gas market and also by the transport market. The Bilateral model is based on decentralized bilateral transactions, by other hand in the Poolco model the transactions are coordinated by just one entity. So, in this model all transactions are centralized.

Tasks and goals of the gas industry in Turkmenistan

Berdiev, N.

1996-01-01

There are two key gas producing regions in central Asia: Amudarinskyi and Murgabskiy. Gas resources in Turkmenistan are light and contain mostly methane. The majority of gas fields are complex: 45 of them contain condensate, 14 helium and ethane, propane and butane. Sulphur dioxide with the total of 893 billion cubic metres is found in 18 gas fields. Within the complex political and economic situation, Turkmen Ministry of Oil and Gas undertook the following measures: technical rehabilitation and refurbishment of the gas industry and research on the gas export pipelines projects. The accounts show that the Turkmen natural gas will find customers in Turkey and other European countries at the prices which will prevail at the time the pipeline is finished. The project costs are 9 billion US dollars and it cannot be finalized without international support

A survey was conducted in April 2001 regarding industry expectations of gas prices, supply, markets, and transportation. The survey involved 97 participants ranging from gas producers, end-users, marketers, pipeline and local distribution companies in North America. The results of the survey can be summarized as follows: Natural gas prices are expected to grow and remain above oil prices through at least 2002. There will continue to be strong growth prospects for North American gas supply, but North American gas storage will be tight for the winter of 2001. North American gas demand is expected to continue to grow. Participants in the survey remained confident that gas demand would continue to grow, despite higher gas prices. Competition from alternative fuels in electricity generation did not appear to be an area of concern for the participants of the survey. 30 figs

The paper is a strategic review of the current environmental policies and practices of the UK Oil and Gas Industry. It begins with an analysis of the current environmental impacts of the UK Oil and Gas Industry, including air emissions, effluents to sea and industrial wastes. The importance of environmental issues to UK operators is related to financial conseqeunces of environmental damage to the North Sea, poor public opinion and the spectre of increased government regulations. There is a survey of the best practices of environmental management programmes, including environmental assessment, monitoring auditing and contingency planning and emergency response, with historical lessons from Cadiz to Valdez and the industry's reaction to Exxon Valdez. After critically assessing the weaknesses of environmental management programmes, the author calls for systematic environmental assessment, employing inventory, monitoring, risk assessment and quantified risk assessment. There are recommendations on how to minimise the impact on the environment through the use of existing technology, training, incident response and crisis management, auditing, testing and industry-wide collaboration.

For the third consecutive year, growth in gas demand is slowing down. The year of 2014 is marked by lower activity in the global gas industry at all stages in the chain. This can be explained by increased competition between energies (coal, renewables), the economic slowdown and the mild weather conditions which have put a brake on expansion of the gas demand (Europe, Asia) and led to high stock levels. These developments have pushed market prices downwards and modified inter-regional balancing flows. (author)

2005-01-01

High-temperature shape-memory alloys (HTSMAs) based on nickel-titanium (NiTi) with significant ternary additions of palladium (Pd), platinum (Pt), gold (Au), or hafnium (Hf) have been identified as potential high-temperature actuator materials for use up to 500 C. These materials provide an enabling technology for the development of "smart structures" used to control the noise, emissions, or efficiency of gas turbine engines. The demand for these high-temperature versions of conventional shape-memory alloys also has been growing in the automotive, process control, and energy industries. However these materials, including the NiPtTi alloys being developed at the NASA Glenn Research Center, will never find widespread acceptance unless they can be readily processed into useable forms.

A comparative study of the adsorption and hydrogenation of acrolein on Pt(1 1 1), Ni(1 1 1) film and Pt Ni Pt(1 1 1) bimetallic surfaces

Science.gov (United States)

Murillo, Luis E.; Chen, Jingguang G.

In this study we have investigated the reaction pathways for the decomposition and hydrogenation of acrolein (CH 2dbnd CH-CH dbnd O) on Ni/Pt(1 1 1) surfaces under ultra-high vacuum (UHV) conditions using temperature programmed desorption (TPD) and high-resolution electron energy loss spectroscopy (HREELS). While gas-phase hydrogenation products are not observed from clean Pt(1 1 1), the subsurface Pt-Ni-Pt(1 1 1), with Ni residing below the first layer of Pt, is active for the self-hydrogenation of the C dbnd O bond to produce unsaturated alcohol (2-propenol) and the C dbnd C bond to produce saturated aldehyde (propanal), with the latter being the main hydrogenation product without the consecutive hydrogenation to saturated alcohol. For a thick Ni(1 1 1) film prepared on Pt(1 1 1), the self-hydrogenation yields for both products are lower than that from the Pt-Ni-Pt(1 1 1) surface. The presence of pre-adsorbed hydrogen further enhances the selectivity toward C dbnd O bond hydrogenation on the Pt-Ni-Pt(1 1 1) surface. In addition, HREELS studies of the adsorption of the two hydrogenation products, 2-propenol and propanal, are performed on the Pt-Ni-Pt(1 1 1) surface to identify the possible surface intermediates during the reaction of acrolein. The results presented here indicate that the hydrogenation activity and selectivity of acrolein on Pt(1 1 1) can be significantly modified by the formation of the bimetallic surfaces.

The potential for Internet commerce in the gas industry

International Nuclear Information System (INIS)

MacLellan, I.

1999-01-01

The potential for Internet commerce in natural gas is examined from the point of view of residential and commercial consumers, government agencies and industry associations, energy marketers and utilities. The overall conclusion of the inquiry is that there are many advantages for everyone concerned, but the few disadvantages that do exist, will delay implementation for a while. Impediments from the consumer's point of view are the natural desire to 'touch and feel' the product purchased, and the reluctance to put a credit card number on the web. The supplier's major reluctance may be that Internet commerce makes product differentiation difficult. The author provides a number of reasons why i nternetting' of the energy industry will eventually become inevitable, as well as tips on how perceived difficulties either do not apply to the gas industry, or can be overcome with only minor changes in attitudes on the part of consumers, and relatively painless adjustments in the way of doing business by suppliers and marketers

The impact of internet-connected control systems on the oil and gas industry

Science.gov (United States)

Martel, Ruth T.

In industry and infrastructure today, communication is a way of life. In the oil and gas industry, the use of devices that communicate with the network at large is both commonplace and expected. Unfortunately, security on these devices is not always best. Many industrial control devices originate from legacy devices not originally configured with security in mind. All infrastructure and industry today has seen an increase in attacks on their networks and in some cases, a very dramatic increase, which should be a cause for alarm and action. The purpose of this research was to highlight the threat that Internet-connected devices present to an organization's network in the oil and gas industry and ultimately, to the business and possibly even human life. Although there are several previous studies that highlight the problem of these Internet-connected devices, there remains evidence that security response has not been adequate. The analysis conducted on only one easily discovered device serves as an example of the ongoing issue of the security mindset in the oil and gas industry. The ability to connect to a network through an Internet-connected device gives a hacker an anonymous backdoor to do great damage in that network. The hope is that the approach to security in infrastructure and especially the oil and gas industry, changes before a major catastrophe occurs involving human life.

This presentation explains what are the most common bottlenecks for foreign investments in the gas industry in Central and Eastern Europe. Taking into account the investment needs arising in economies in transition, from investor's point of view the issue of great importance is the risk when prices are not yet at market equivalent levels. Changes in the policy (regulatory, legal, financial) environment should stimulate investments. Privatization and liberalization are also driven by lack of public capital. Foreign investment would need a predictable investment environment. The investment needs of the gas industry would compete with other investments that might be more attractive

1998-01-01

Transportation and distribution of natural gas in Mexico are undergoing fundamental changes as a result of the 1995 passage by the Congress of Mexico of the law that created the Energy Regulatory Commission (Comision Reguladora de Energia--CRE). The law mandates that the commission must achieve a competitive, efficient, safe, and sustainable gas industry, allowing the country to make the difficult energy transition to open gas and electricity markets relying on cleaner fuels. The paper discusses the situation before CRE, the regulatory framework, market development, and the North American market

Pt-Ni and Pt-Co Catalyst Synthesis Route for Fuel Cell Applications

Firdosy, Samad A.; Ravi, Vilupanur A.; Valdez, Thomas I.; Kisor, Adam; Narayan, Sri R.

Oxygen reduction reactions (ORRs) at the cathode are the rate-limiting step in fuel cell performance. The ORR is 100 times slower than the corresponding hydrogen oxidation at the anode. Speeding up the reaction at the cathode will improve fuel cell efficiency. The cathode material is generally Pt powder painted onto a substrate (e.g., graphite paper). Recent efforts in the fuel cell area have focused on replacing Pt with Pt-X alloys (where X = Co, Ni, Zr, etc.) in order to (a) reduce cost, and (b) increase ORR rates. One of these strategies is to increase ORR rates by reducing the powder size, which would result in an increase in the surface area, thereby facilitating faster reaction rates. In this work, a process has been developed that creates Pt-Ni or Pt-Co alloys that are finely divided (on the nano scale) and provide equivalent performance at lower Pt loadings. Lower Pt loadings will translate to lower cost. Precursor salts of the metals are dissolved in water and mixed. Next, the salt mixtures are dried on a hot plate. Finally, the dried salt mixture is heattreated in a furnace under flowing reducing gas. The catalyst powder is then used to fabricate a membrane electrode assembly (MEA) for electrochemical performance testing. The Pt- Co catalyst-based MEA showed comparable performance to an MEA fabri cated using a standard Pt black fuel cell catalyst. The main objective of this program has been to increase the overall efficiencies of fuel cell systems to support power for manned lunar bases. This work may also have an impact on terrestrial programs, possibly to support the effort to develop a carbon-free energy source. This catalyst can be used to fabricate high-efficiency fuel cell units that can be used in space as regenerative fuel cell systems, and terrestrially as primary fuel cells. Terrestrially, this technology will become increasingly important when transition to a hydrogen economy occurs.

According to a survey conducted by the Ziff Energy Group, industry insiders are optimistic about natural gas supply and demand during 2000. The survey, which was designed to provide an integrated description of the North American gas industry from wellhead to burner tip, covered 124 companies across North America. Slightly more than half of the U.S. respondents expect to produce at least five per cent more natural gas in 2000 than the previous year, while 19 per cent of the respondents expect production increases to exceed 15 per cent. Among Canadian respondents, some 70 per cent expect production to increase five per cent; another 25 per cent anticipate increases in production to reach or exceed 15 per cent. Canadian natural gas export to the United States are expected to grow by up to 700 million cubic feet per day by almost 50 per cent of Canadian respondents; one third of the respondents expect exports to increase by 700 to 900 million cubic feet per day. Growth in U.S. demand for natural gas are predicted to be moderate in 2000, and increase somewhat in 2001. Canadian growth in sales is expected to be in the one-to-two per cent range. Few of the respondents expect gas prices to decline, and few are concerned that gas prices may put sales at risk. The majority of respondents believe that gas supply growth poses the greatest challenge to increasing pipeline capacity

Natural gas industry faces more uncertainty in the upcoming decade

Steffes, D.W.

The monumental discontinuity of the past decade in the natural gas industry was the change of the interstate gas pipeline industry from serving as a merchant function to a common carrier function. The main reason this change could come about was a past strategic error on the part of the interstate pipeline companies. In the early 1980s, they misread the gas supply signals and entered into uneconomical take or pay contracts at unreasonably high prices. This strategic mistake essentially bankrupted all of the pipeline companies. Their submittal to the Federal Energy Regulatory Commission (FERC) forced them to allow open access on their pipelines. The FERC then allowed them to buy their way out of their bad take or pay contracts. The method of pricing natural gas at the wellhead was the other big change. Instead of the major interstate pipeline continuing with a form of mandating area rates, each producer can now deal directly with anyone wanting to purchase the gas. The transportation is available due to these pipelines becoming common carriers. These two discontinuities allowed new paper interstate pipelines to come into existence

Catalytic oxidation of NO to NO{sub 2} is a significant research interest for improving the quality of air through exhaust gas purification systems. In this paper, the authors studied this reaction on pure Pt and Pt overlayer on 3d transition metals using kinetic Monte Carlo simulations coupled with density functional theory based first principles calculations. The authors found that on the Pt(111) surface, NO oxidation proceeds via the Eley–Rideal mechanism, with O{sub 2} dissociative adsorption as the rate-determining step. The oxidation path via the Langmuir–Hinshelwood mechanism is very slow and does not significantly contribute to the overall reaction. However, in the Pt overlayer systems, the oxidation of NO on the surface is more thermodynamically and kinetically favorable compared to pure Pt. These findings are attributed to the weaker binding of O and NO on the Pt overlayer systems and the binding configuration of NO{sub 2} that promotes easier N-O bond formation. These results present insights for designing affordable and efficient catalysts for NO oxidation.

Canadian oil and gas industry competitiveness and financial performance update 2002

Tertzakian, P.; Baynton, K.

2002-08-01

This report presents an independent assessment of profitability in the upstream Canadian petroleum industry. The upstream sector includes exploration and production of oil and gas reserves. This report offers a historical and a forward looking perspective on the financial performance of the industry in 2001. The performance of the industry is compared with other industries in Canada and around the world. The report is divided into the following 4 sections: (1) how capital flows in the Canadian upstream oil and gas economy, (2) the analysis of sector profitability based on the efficiency of capital flow in section 1, (3) how the profitability of the Canadian upstream oil and gas sector stands up compared to other industries, and (4) appendices and other supplementary information. It was noted that as geologic basins are developed, non-renewable resources continue to become more capital intense, a phenomenon that is very evident in the Western Canada Sedimentary Basin. The industry must provide financial incentives for investors to participate in exploration and development. The return on capital must exceed the cost of capital in order to maintain that incentive. The principal findings of this report include: (1) a higher than average uncertainty and volatility expected in 2003, (2) operating costs vary with production, but finding and developing costs are still increasing, (3) declining conventional reserves, (4) growing non-conventional expenditures, (5) current taxes cut into margins, (6) cost of capital only achievable with firm commodity prices, (7) in comparison to other industries, years 2000 and 2001 are exceptional for the industry with high commodity prices catalyzing returns greater than other countries. tabs., figs

Controversies about gas industry deregulation in Europe

International Nuclear Information System (INIS)

Percebois, J.

1992-01-01

The E.E.C. Commission wishes to introduce more competition into the European gas industry; abolish import public monopolies, resort to competitive bidding for distribution concessions, and to the common carrier system in the transport field. This deregulation policy may induce adverse effects in the long run. This may compromise supply security, and delay the development of new gas fields. This may particularly induce subsidies among users and lead to a reinforcement of regulation if we want the Third Party Access system to respect equality conditions for all users. This paper analyzes arguments for and against this common carrier system. 15 refs., 2 figs

Technological acceleration and organizational transformations in the upstream oil and gas industry

International Nuclear Information System (INIS)

Isabelle, M.

2000-12-01

The upstream oil and gas industry experienced a dramatic technological acceleration in the early 1970's. The relationships between the agents in this industry have themselves undergone deep changes since that date. This thesis shows that a tight link exists between the technological acceleration and the organizational transformations in the upstream oil and gas industry. In a first part, it focuses on the economic theory's developments concerning industrial organization. In a second part, it applies these developments to three types of relations: those between the owner-states of hydrocarbon resources and the international petroleum companies; those between the international petroleum companies and their subcontractors; and finally those between the international petroleum companies themselves.

The insurance industry and unconventional gas development: Gaps and recommendations

International Nuclear Information System (INIS)

Wetherell, Daniel; Evensen, Darrick

2016-01-01

The increasingly growing and controversial practice of natural gas development by horizontal drilling and high volume hydraulic fracturing (‘fracking’) faces a severe environmental insurance deficit at the industry level. Part of this deficit is arguably inherent to the process, whereas another part is caused by current risk information shortfalls on the processes and impacts associated with development. In the short and long terms, there are several conventional and unconventional methods by which industry-level and governmental-level policy can insure against these risks. Whilst academic attention has been afforded to the potential risks associated with unconventional natural gas development, little consideration has been given to the lack of insurance opportunities against these risks or to the additional risks promulgated by the dearth of insurance options. We chronicle the ways in which insurance options are limited due to unconventional gas development, the problems caused by lack of insurance offerings, and we highlight potential policy remedies for addressing these gaps, including a range of government- and industry-specific approaches. - Highlights: •A gap exists in provision of liability insurance for ‘fracking’-related risks. •The market gap is due primarily to uncertainties about probabilistic risk. •Insurance for risks similar to ‘fracking’ highlight potential policy options. •Government regulation and/or industry agreements can effectively fill the gap. •Policies on insurance and liability coverage necessitate ethical considerations.

2000-07-01

This paper presents a case study of the development of the gas industry in Trinidad and Tobago. Recognition is given to State's role in providing a friendly regulatory, administrative and fiscal regime for investment in the upstream and downstream sectors and that of the National Gas Company of Trinidad and Tobago Limited in the promotion and development of Natural Gas Based Industries. At present, initiatives for additional gas based industries are ongoing and it is expected that this portfolio of gas utilization will be expanded to include Aluminum manufacture, additional LNG, Methanol, Ammonia, Iron reduction and Steel manufacture and Ethylene. The provision of infrastructure to support these industries include a phased development of gas transmission network, industrial estates with multi-user piers and harbour facilities for export based projects. The evolution of an energy policy framework within which the full potential of the nation's energy resources can be realized is viewed as crucial to the development of the industry. The gas pricing policy used in conjunction with other factors provide a competitive advantage for foreign investment in gas based industries and have served to attract gas based manufacturing facilities. The country has realized employment opportunities, export earnings and increased financial and economic activities from these investments. (authors)

US Department of Energy investments in natural gas R ampersand D: An analysis of the gas industry proposal

International Nuclear Information System (INIS)

Sutherland, R.J.

1992-01-01

The natural gas industry has proposed an increase in the DOE gas R ampersand D budget from about $100 million to about $250 million per year for each of the next 10 years. The proposal includes four programs: natural gas supplies, fuel cells, natural gas vehicles and stationary combustion systems. This paper is a qualitative assessment of the gas industry proposal and recommends a natural gas R ampersand D strategy for the DOE. The methodology is a conceptual framework based on an analysis of market failures and the energy policy objectives of the DOE's (1991) National Energy Strategy. This framework would assist the DOE in constructing an R ampersand D portfolio that achieves energy policy objectives. The natural gas supply program is recommended to the extent that it contributes to energy price stability. Stationary combustion programs are supported on grounds of economic efficiency and environmental quality. The fuel cell program is supported on grounds of environmental quality. The natural gas vehicle program may potentially contribute to environmental quality and energy price stability. The R ampersand D programs in natural gas vehicles and in fuel cells should be complemented with policies that encourage the commercialization and use of the technology, not merely its development

Investment and uncertainty in the international oil and gas industry

International Nuclear Information System (INIS)

Mohn, Klaus; Misund, Baard

2009-01-01

The standard theory of irreversible investments and real options suggests a negative relation between investment and uncertainty. Richer models with compound option structures open for a positive relationship. This paper presents a micro-econometric study of corporate investment and uncertainty in a period of market turbulence and restructuring in the international oil and gas industry. Based on data for 115 companies over the period 1992-2005, we estimate four different specifications of the q model of investment, with robust results for the uncertainty variables. The estimated models suggest that macroeconomic uncertainty creates a bottleneck for oil and gas investment and production, whereas industry-specific uncertainty has a stimulating effect. (author)

EFFECTS OF OIL AND NATURAL GAS PRICES ON INDUSTRIAL PRODUCTION IN THE EUROZONE MEMBER COUNTRIES

Directory of Open Access Journals (Sweden)

Yılmaz BAYAR

2014-04-01

Full Text Available Industrial production is one of the leading indicators of gross domestic product which reflects the overall economic performance of a country. In other words decreases or increases in industrial production point out a contracting or expanding economy. Therefore, changes in prices of oil and natural gas which are the crucial inputs to the industrial production are also important for the overall economy. This study examines the effects of changes in oil and natural gas prices on the industrial production in the 18 Eurozone member countries during the period January 2001-September 2013 by using panel regression. We found that oil prices and natural gas prices had negative effect on industrial production in the Eurozone member countries.

China’s industrial boiler systems consume 700 million tons of coal annually, accounting for 18% of the nation’s total coal consumption. Together these boiler systems are one of the major sources of China’s greenhouse gas (GHG) emissions, producing approximately 1.3 gigatons (Gt) of carbon dioxide (CO₂) annually. These boiler systems are also responsible for 33% and 27% of total soot and sulfur dioxide (SO2) emissions in China, respectively, making a substantial contribution to China’s local environmental degradation. The Chinese government - at both the national and local level - is taking actions to mitigate the significant greenhouse gas (GHG) emissions and air pollution related to the country’s extensive use of coal-fired industrial boilers. The United States and China are pursuing a collaborative effort under the U.S.-China Climate Change Working Group to conduct a comprehensive assessment of China’s coal-fired industrial boilers and to develop an implementation roadmap that will improve industrial boiler efficiency and maximize fuel-switching opportunities. Two Chinese cities – Ningbo and Xi’an – have been selected for the assessment. These cities represent coastal areas with access to liquefied natural gas (LNG) imports and inland regions with access to interprovincial natural gas pipelines, respectively.

Gregory D. Gillispie

1997-12-01

This document has been developed for the nontechnical gas industry manager who has the responsibility for the development of waste or potentially contaminated soil and groundwater data or must make decisions based on such data for the management or remediation of these materials. It explores the pse of common analytical chemistry instrumentation and associated techniques for identification of environmentally hazardous materials. Sufficient detail is given to familiarize the nontechnical reader with the principles behind the operation of each technique. The scope and realm of the techniques and their constituent variations are portrayed through a discussion of crucial details and, where appropriate, the depiction of real-life data. It is the author's intention to provide an easily understood handbook for gas industry management. Techniques which determine the presence, composition, and quantification of gas industry wastes are discussed. Greater focus is given to traditional techniques which have been the mainstay of modem analytical benchwork. However, with the continual advancement of instrumental principles and design, several techniques have been included which are likely to receive greater attention in fiture considerations for waste-related detection. Definitions and concepts inherent to a thorough understanding of the principles common to analytical chemistry are discussed. It is also crucial that gas industry managers understand the effects of the various actions which take place before, during, and after the actual sampling step. When a series of sample collection, storage, and transport activities occur, new or inexperienced project managers may overlook or misunderstand the importance of the sequence. Each step has an impact on the final results of the measurement process; errors in judgment or decision making can be costly. Specific techniques and methodologies for the collection, storage, and transport of environmental media samples are not

McClure, D.C.

1992-01-01

Many in the energy industry thought the natural gas buying game had finally settled down to a predictable pattern in the 90's. After a tumultuous decade in the 80's they are ready to turn their attention to new challenges such as electricity wheeling and cogeneration. They were wrong. There is plenty of change left in the natural gas industry for the rest of the century. This growth will dramatically increase the number of options available to Energy Buyers, giving them new flexibility to design programs that meet goals for cost reduction, supply reliability, and administrative effort. However, with new options also come the responsibility for choices. Energy Managers of well designed gas programs will make these choices after careful consideration of the pro's and con's of each option. In short, the effective Buyer will develop a natural gas strategy. This report will begin by reviewing the basic types of change occurring in the industry, and then discuss some of the varied strategy options available to the Energy Buyer

Effect of Ce on performance and physicochemical properties of Pt-containing automotive emission control catalysts

International Nuclear Information System (INIS)

Nunan, J.G.; Silver, R.G.; Bradley, S.A.

1992-01-01

Present-day automotive emission control catalysts contain noble metals such as Pt, Pd and Rh all on an alumina support with a variety of promoters. Ce is one of the most important promoters. In this paper, the interaction between Pt and Ce is studied using TPR and STEM on a variety of catalysts. The degree of Pt/Ce interaction is increased by decreasing CeO 2 crystallite size, and to a lesser extent by increasing CeO 2 loading. Direct Pt/Ce interaction leads to a synergistic reduction of both Pt and surface Ce. This reduction qualitatively correlates with catalyst performance after activation in a reducing gas. It is proposed that this synergistic reduction of Pt and Ce is associated with observed improvements in catalyst performance using a non-oscillating exhaust gas

Industrial natural gas consumption in the United States: an empirical model for evaluating future trends

International Nuclear Information System (INIS)

Huntington, H.G.

2007-01-01

This study develops a statistical model of industrial US natural gas consumption based upon historical data for the 1958-2003 period. The model specifically addresses interfuel substitution possibilities and changes in the industrial economic base. Using a relatively simple approach, the framework can be simulated repeatedly with little effort over a range of different conditions. It may also provide a valuable input into larger modeling exercises where an organization wants to determine long-run natural gas prices based upon supply and demand conditions. Projections based upon this demand framework indicate that industrial natural gas consumption may grow more slowly over the next 20 yr than being projected by the U.S. Energy Information Administration (EIA). This conclusion is based upon the assumption that natural gas prices will follow oil prices, as they have done over recent decades. If natural gas prices should lag well below oil prices, as envisioned by the latest EIA outlook, industrial natural gas consumption should rapidly expand well beyond the levels being projected by EIA.

Wetland mitigation banks are already in existence in the United States, and the number is increasing. To date, most of these banks have been created and operated for mitigation of impacts arising from highway or commercial development and have not been associated with the oil and gas industry. Argonne National Laboratory evaluated the positive and negative aspects of wetland mitigation banking for the oil and gas industry by examining banks already created for other uses by federal, state, and private entities. Specific issues addressed in this study include (1) the economic, ecological, and technical effectiveness of existing banks; (2) the changing nature of local, state, and federal jurisdiction; and (3) the unique regulatory and jurisdictional problems affecting bank developments associated with the oil and gas industry.

A comparison of the structure and organisation of the West German and the U. S. gas industries. Consequences for the status of gas utility companies

When comparing the West German gas industry to the United States one finds some striking differences in their structure and organisation. The German industry is small but growing, vertically integrated, efficient and scarcely regulated. The US-industry is big, hardly integrated and just recovering from years of frictions caused by successive waves of misguided regulations which were interrupted only by short periods of deregulation. Violation of contracts, price rises, price dumps, 'evasions', law suits are characteristic of today's American gas industry. The history of regulations in the U.S. gas industry is a nightmare other countries have fortunately been able to avoid. (orig.).

There have been a number of restraints in Japan delaying the introduction of natural gas vehicles (NGVs), which is a new comer in car industry. The Japanese gas industry, with support from government agencies, has conducted feasibility studies and clarified necessary technical and safety standards and regulations. These efforts have contributed to the government's drive for deregulation. Concurrently, the gas industry worked out its own scenarios for the promotion of NGVs in Japan, which helped the government in laying down necessary regulations and establishing clear market objectives for the vehicles as government policies. Such activities have yielded model introduction by the national and local governments and government-sponsored incentives for NGV promotion. For auto manufacturers, the gas industry proposed joint development projects and clarified potential market for NGVs. Consequently, many manufactures are now involved in their own NGV development projects. (au)

Graphical abstract: Direct-grown boron-doped carbon nanotubes on gas-diffusion layer as efficient Pt-free cathode catalyst for alcohol fuel cells, high boiling point fuels used to obtain hot fuels for the enhancement of cell performance that paves the way for the utilization of waste heat. Display Omitted -- Highlights: •One-step direct synthesis of boron-doped carbon nanotubes (BCNTs) on gas diffusion layer (GDL). •Home built fuel-cell testing using BCNTs on GDL as Pt-free cathode catalyst. •BCNTs exhibit concentration dependent oxygen reduction reaction and the cell performance. •Effective utilization of waste heat to raise the fuel temperature. •Fuel selectivity to raise the fuel temperature and the overall performance of the fuel cells. -- Abstract: Gas diffusion layers (GDL) and electrocatalysts are integral parts of fuel cells. It is, however, a challenging task to grow Pt-free robust electrocatalyst directly on GDL for oxygen reduction reaction (ORR) – a key reaction in fuel cells. Here, we demonstrate that boron-doped carbon nanotubes (BCNTs) grown directly on gas-diffusion layer (which avoid the need of ionomer solution used for catalyst loading) can be used as efficient Pt-free catalyst in alcohol fuel cells. Increase in boron concentration improves the electrochemical ORR activity in terms of onset and ORR peak positions, half-wave potentials and diffusion-limited current density that ensure the optimization of the device performance. The preferential 4e − pathway, excellent cell performance, superior tolerance to fuel crossover and long-term stability makes directly grown BCNTs as an efficient Pt-free cathode catalyst for cost-effective fuel cells. The maximum power density of the fuel cell is found to increase monotonically with boron concentration. In addition to the application of BCNTs in fuel cell, we have introduced the concept of hot fuels so that waste heat can effectively be used and external power sources can be avoided. The fuel

Highlights: • Novel semiconductors decorated by CdTe QDs and/or Pt NPs were synthesized. • Photodeposition and radiolysis is an effective method to obtaining Pt NPs. • CdTe decorated samples were prepared by absorption of QDs on matrix surface. • KTaO{sub 3}/CdTe-Pt{sub (R)} showed highest photocatalytic performance. • The enhanced performance was associated with electron trap mechanism. - Abstract: A novel synthesis process was used to prepare TiO{sub 2} microspheres, TiO{sub 2} P-25, SrTiO{sub 3} and KTaO{sub 3} decorated by CdTe QDs and/or Pt NPs. The effect of semiconductor matrix, presence of CdTe QDs and/or Pt NPs on the semiconductor surface as well as deposition technique of Pt NPs (photodeposition or radiolysis) on the photocatalytic activity were investigated. The as-prepared samples were characterized by X-ray powder diffractometry (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM) with energy-dispersive X-ray (EDX) spectroscopy, scanning electron microscopy (SEM), photoluminescence spectrometry (PL), Fourier transform infrared (FT-IR) and Raman spectra, diffuse reflectance spectroscopy (DRS) and BET surface area analysis. The photocatalytic decomposition of toluene in gas phase, activated by light-emitting diodes (LEDs), with the CdTe/Pt nanoparticles-modified TiO{sub 2} microspheres, P25, SrTiO{sub 3} and KTaO{sub 3} semiconductors was investigated under UV–vis and visible irradiation.The results showed that the photoactivity depends on semiconductor matrix. The highest photoactivity under Vis light was observed for KTaO{sub 3}/CdTe-Pt{sub (R)} sample (56% of toluene was decompose after 30 min of irradiation). The efficiency of the most active sample was 3 times higher than result for P25 and two times higher than for unmodified KTaO{sub 3}.

PtSnCu/C (with different Pt:Sn:Cu atomic ratios) and PtSn/C (50:50) electrocatalysts were prepared by borohydride (BR) and alcohol-reduction (AR) processes using H 2 PtCl 6 .6H 2 O, SnCl 2 .2H 2 O and CuCl 2 .2H 2 O as metal sources, NaBH 4 and ethylene glycol as reducing agents, 2-propanol and ethylene glycol/water as solvents and carbon black as support. In a further step, these electrocatalysts were activated by chemical (CD) and electrochemical (ED) dealloying processes through acid treatment and thin porous coating technique, respectively. These materials were characterized by energy dispersive X-ray, Xray diffraction, transmission electron microscopy, line scan energy dispersive Xray and cyclic voltammetry. Electrochemical studies for ethanol electro-oxidation were performed by cyclic voltammetry, chronoamperometry and in single Direct Ethanol Fuel Cell using Membrane Electrode Assembly (MEA). The anodic effluents were analysed by gas chromatography. The X-ray diffractograms of the as-synthesized electrocatalysts showed the typical face-centered cubic structure (FCC) of platinum and its alloys. After dealloying, the X-ray diffractograms showed that the Pt FCC structure was preserved. The crystallite sizes of the assynthesized electrocatalysts were in the range of PtSnCu/C (50:40:10) AR/ED > PtSnCu/C (50:10:40) BR/CD. PtSn/C (50:50) BR/CD, PtSnCu/C (50:10:40) BR/CD, PtSnCu/C (50:40:10) AR/CD electrocatalysts and Pt/C BASF, PtSn/C (75:25) BASF commercial electrocatalysts were tested in single Direct Ethanol Fuel Cell. The results showed the following performance for ethanol electro-oxidation: PtSn/C (50:50) BR/CD > PtSnCu/C (50:40:10) AR/CD > PtSnCu/C > PtSn/C (75:25) BASF > PtSnCu/C (50:10:40) BR/CD > Pt/C BASF.

Oxide-supported precious metal nanoparticles are widely used industrial catalysts. Due to expense and rarity, developing synthetic protocols that reduce precious metal nanoparticle size and stabilize dispersed species is essential. Supported atomically dispersed, single precious metal atoms represent the most efficient metal utilization geometry, although debate regarding the catalytic activity of supported single precious atom species has arisen from difficulty in synthesizing homogeneous and stable single atom dispersions, and a lack of site-specific characterization approaches. We propose a catalyst architecture and characterization approach to overcome these limitations, by depositing ∼1 precious metal atom per support particle and characterizing structures by correlating scanning transmission electron microscopy imaging and CO probe molecule infrared spectroscopy. This is demonstrated for Pt supported on anatase TiO 2 . In these structures, isolated Pt atoms, Pt iso , remain stable through various conditions, and spectroscopic evidence suggests Pt iso species exist in homogeneous local environments. Comparing Pt iso to ∼1 nm preoxidized (Pt ox ) and prereduced (Pt metal ) Pt clusters on TiO 2 , we identify unique spectroscopic signatures of CO bound to each site and find CO adsorption energy is ordered: Pt iso ≪ Pt metal atoms bonded to TiO 2 and that Pt iso exhibits optimal reactivity because every atom is exposed for catalysis and forms an interfacial site with TiO 2 . This approach should be generally useful for studying the behavior of supported precious metal atoms.

The Relationship Between Oil and Gas Industry Investment in Alternative Energy and Corporate Social Responsibility

Science.gov (United States)

Konyushikhin, Maxim

The U.S. Energy Information Administration forecasted energy consumption in the United States to increase approximately 19% between 2006 and 2030, or about 0.7% annually. The research problem addressed in this study was that the oil and gas industry's interest in alternative energy is contrary to its current business objectives and profit goals. The purpose of the quantitative study was to explore the relationship between oil and gas industry investments in alternative energy and corporate social responsibilities. Research questions addressed the relationship between alternative energy investment and corporate social responsibility, the role of oil and gas companies in alternative energy investment, and why these companies chose to invest in alternative energy sources. Systems theory was the conceptual framework, and data were collected from a sample of 25 companies drawn from the 28,000 companies in the oil and gas industry from 2004 to 2009. Multiple regression and correlation analysis were used to answer the research questions and test hypotheses using corporate financial data and company profiles related to alternative energy investment and corporate social responsibility in terms of oil and gas industry financial support of programs that serve the greater social good. Results indicated significant relationships between alternative energy investment and corporate social responsibility. With an increasing global population with energy requirements in excess of what is available using traditional means, the industry should increase investment in alternative sources. The research results may promote positive social change by increasing public awareness regarding the degree to which oil and gas companies invest in developing alternative energy sources, which might, in turn, inspire public pressure on companies in the oil and gas industry to pursue use of alternative energy.

For the last 20 years, countless countries have been carrying out structural reforms in the natural gas industry, trying to achieve efficiency and economic rationality with the introduction of competition. The objective of the paper is to present an approach to the development of competition and infrastructure of the Brazilian natural gas industry. This approach is based on a market projection to 2011, on the international experience and on the characteristics of the Brazilian market, infrastructure and regulatory framework. Possible impacts of the proposed measures are also provided. According to the market projection carried out in this paper, in 2011 there will be a possible surplus of natural gas in the country, which includes a dependence diminishing of the Bolivian gas supply. This gas surplus, allied to an upcoming Gas Law and the trade liberalization in the states of Sao Paulo and Rio de Janeiro, can stimulate the development of competition, if some changes that proposed in this paper are made in the current Gas Bills. The approach proposed herein seeks to stimulate non-discriminatory open access, focused on information transparency and tariff regulation to help the development of infrastructure and competition.

The objective of this paper was to evaluate the performance of the natural gas industry using an inter-country comparison of productivity level and its determinants. Three methodologies: multilateral Toernqvist productivity analysis; managerial index system analysis; and non-parametric efficiency analysis, are employed to make a methodological cross-checking and to perform diversified analysis. From the empirical results, we identified the level and growth rate of productivity of individual firms. The results also indicated that the Korean gas industry has shown a relatively low level of productivity. From the results of managerial performance index analysis, we found that during the recent years of regulatory changes, the final price of gas has decreased dramatically while the productivity growth has not been enough to offset the effect of decreased output price, which has resulted in decreased profit. We also examine the extent of the allocative, scale, and managerial efficiency as source components of the overall efficiency based on the performance of best-practiced. With the results of this study, an effective policy measure could be established to improve the productivity and the overall managerial performance in the natural gas industry

Some basic facts regarding derivatives in the electric power industry were discussed based on experiences in the natural gas industry. Derivatives were described as financial instruments that have no value of their own but derive their value from other assets, such as commodities. Futures and Options are the two forms of derivatives. Electricity as a commodity was characterized, and a historical parallel was drawn between deregulation in the natural gas and electric power industry. Short term and long term factors impacting the market and market dynamics impacting derivatives were identified. The latter include: (1) volatility, (2) liquidity, (3) correlations, and (4) price discovery. In contrast to the natural gas market, the electricity market is considered as lacking liquidity and in need of moving farther along the maturity timeline. The question of natural gas/ electricity convergence was also addressed refs., tabs., figs

The natural gas industry will confront many challenges in the 1990s and beyond, one of which is the development of human resources to meet future needs. An efficient, trained work force in this era of environmental concern, high technology, and alternative fuels is essential for the industry to continue to meet the competition and to safely deliver our product and service to all customers. Unfortunately, during this period there will be an increasing shortfall of technical personnel to replace those lost to attrition and a steady decline in the availability of new employees who are able to read, write, and perform simple math. Technological and government developments that will impact the industry and the skill levels needed by the industry employees are reviewed. In-house and external training of professional and nonprofessional personnel and the benefits and disadvantages of selected advanced training methods are discussed. Recommendations are presented that can help improve the training of gas industry employees to meet future needs. 22 refs

Electrochemical promotion of catalytic reactions with Pt/C (or Pt/Ru/C)//PBI catalysts

The paper is an overview of the results of the investigation on electrochemical promotion of three catalytic reactions: methane oxidation with oxygen, NO reduction with hydrogen at 135 degrees C and Fischer-Tropsch synthesis (FTS) at 170 degrees C in the [CH4/O-2(or NO/H-2 or CO/H-2)/Ar//Pt(or Pt....../Ru)//PBI(H3PO4)/H-2, Ar] fuel cell. It has been shown that the partial methane oxidation to C2H2 and the C-2 selectivity were electrochemically promoted by the negative catalyst polarization. This was also the case in NO reduction with hydrogen for low NO and H-2 partial pressures. In both cases the catalytic...... reactions have been promoted by the electrochemically produced hydrogen. It has been found that the NO reduction with hydrogen on the Pt/PBI strongly depends on NO and hydrogen partial pressures in the working gas mixture. At higher NO and H-2 partial pressures the catalysis is promoted...

Natural gas industry and its effects on the environment

Al-Masri, M. S.; Kejeijan, B.

2008-01-01

The discoveries of natural gas have increased during the last ten years in Syria, These increases lead to the necessity of knowing the effects of this industry on the environment. Syrian Arabic Republic has been planning to convert most of the current electric of plants to natural gas in addition to future plans to export natural gas to the surrounding countries. In addition, the government is working on the use of LPG gas in automobiles. However, environmentally, the importance of natural gas is due to the followings: 1- Natural gas, when burned, emits lower quantities of greenhouse gases and criteria pollutants per unit of energy produced than to other fossil fuels. This occurs in part because natural gas is more fully combusted, and in part because natural gas contains fewer impurities than any other fossil fuel. 2-The amount of carbon dioxide produced from the combustion of natural gas is less than the amount produced from the combustion of other fossil fuels to produce the same amount of heat. One of the important uses of natural gas is in the transportation since natural gas does not produce during combustion toxic compounds which are usually produced during the combustion of diesel and benzene. therefore natural gas is seen and considered as an important fuel to address environmental concerns.

A first article outlines that the exploitation of shale gases would favour a competitiveness boost for the industry (notably for the electricity sector, the chemical sector and other sectors depending on them), but that environmental drawbacks and European characteristics could also limit this boost. The author evokes activities of shale gas exploitation in the USA and their consequences in terms of gas prices, or for extraction equipment manufacturers or for the chemical industry. The different issues are discussed: environment, global warming, and energy supply. A second article describes the main shale gas sites in Texas notably that of Fort Worth which is within the city itself. A third article reports the struggle of Dordogne local authorities and citizen associations against projects of shale gas exploitation by hydraulic fracturing. As this extraction process is forbidden in France, a last article outlines that the development of another technique would require ten more years. Some perspectives are evoked

Liberalization and enlargement: impacts on the industrial organisation of natural gas markets in Eastern Europe

International Nuclear Information System (INIS)

Pirovska, M.

2004-01-01

In 2004, the EU has opened its commercial natural gas industry to competition, while eight former socialist countries have become member states. This ongoing institutional evolution is expected to have a great impact on the industrial organisation of the East European natural gas markets. Specificities and rigidities of the transport networks, as well as strong import dependency may in fact weaken the security of supply and confirm that natural gas is strongly affected by geopolitical constraints. By levering on an analysis of structure and strategies across natural gas markets in Eastern Europe, this dissertation explores the stakes of integration and liberalization on the industrial organisation of European natural gas and reveals the risk of an emerging oligopoly, and the cooperation between dominant players. Our main contention is that this evolution could possibly hinder network interconnection thereby thwarting the achievement of an integrated and single competitive natural gas market in the Union.

Impact of improved technology on industrial greenhouse-gas emissions in developing countries. Phase 1

International Nuclear Information System (INIS)

1997-06-01

In response to a formal request by the Group of 77 and China, the United Nations Industrial Development Organization (UNIDO) initiated a study to identify opportunities to reduce the emissions of greenhouse gases from energy-intensive industries in developing countries. These sectors currently include iron and steel, petroleum refining, cement, paper and pulp and nitrogen fertilizers. The aim of this first phase was to describe: how energy is used in the energy-intensive industries in developing countries today; what current trends indicate for the future; the potential contribution of improved technologies and practices to moving toward more sustainable industrial production in developing countries, and to provide developing countries with an analytical tool for evaluating opportunities to limit industrial greenhouse-gas (GHG) emissions in their industrial sectors through the transfer of improved technologies and processes. The immediate objectives of Phase 1 were twofold: to provide information to developing countries in the form of an inventory of energy-efficient, best-available technologies and processes that can be used to abate greenhouse-gas emissions in the most energy-intensive industrial sub-sectors as well as cross-cutting measures applicable in a range of sub-sectors, and; to provide an analytical methodology in the form of a software tool that enables the user to evaluate and compare the costs, energy requirements, and greenhouse-gas emissions associated with scenarios of specific technology and process options. To meet these objectives, the first phase of the study comprised: a Report entitled Industrial Greenhouse-gas Emissions from Developing Countries; a Software Package containing, an Industrial Technology Inventory, and an Analysis Tool, and; Industry/country-specific Case Studies. The Report describes current energy use and greenhouse-gas emissions in energy-intensive industries in developing countries, and similar industries exemplifying good

One of the main challenges in the energy transition is to integrate the increasing based on volatile renewable energy generated power in market and network. Based on actual distribution networks in Emsland in the study presented below was investigated, what contribution an intelligent coupling of electricity and gas distribution networks by means of power to gas (PtG) systems can do to solve this challenge. The investigations have shown, among other things, that the network expansion costs in particular can be significantly reduced by the coupling when otherwise an oversizing would be done by discrete power grid expansion measures. [German] Eine der wesentlichen Herausforderung bei der Energiewende besteht darin, die zunehmend auf volatilen erneuerbaren Energien basierende Stromerzeugung in Markt und Netz zu integrieren. Anhand realer Verteilungsnetze im Emsland wurde in der im Folgenden vorgestellten Studie untersucht, welchen Beitrag eine intelligente Kopplung von Strom- und Gasverteilungsnetzen mittels Power-to-Gas (PtG)-Anlagen zur Loesung dieser Herausforderung leisten kann. Die Untersuchungen haben unter anderem gezeigt, dass durch die Kopplung die Netzausbaukosten insbesondere dann signifikant reduziert werden koennen, wenn andernfalls eine Ueberdimensionierung durch diskrete Stromnetzausbaumassnahmen erfolgen wuerde.

Energy generation and consumption are the main contributors to greenhouse gases emissions in California. Natural gas is one of the primary sources of energy in California. A study was recently conducted to develop current, reliable, and California-specific source emission factors (EFs) that could be used to establish a more accurate methane emission inventory for the California natural gas industry. Twenty-five natural gas facilities were surveyed; the surveyed equipment included wellheads (172), separators (131), dehydrators (17), piping segments (145), compressors (66), pneumatic devices (374), metering and regulating (M&R) stations (19), hatches (34), pumps (2), and customer meters (12). In total, 92,157 components were screened, including flanges (10,101), manual valves (10,765), open-ended lines (384), pressure relief valves (358), regulators (930), seals (146), threaded connections (57,061), and welded connections (12,274). Screening values (SVs) were measured using portable monitoring instruments, and Hi-Flow samplers were then used to quantify fugitive emission rates. For a given SV range, the measured leak rates might span several orders of magnitude. The correlation equations between the leak rates and SVs were derived. All the component leakage rate histograms appeared to have the same trend, with the majority of leakage ratesGas Research Institute (EPA/GRI) study. Twenty-five natural gas facilities in California were surveyed to develop current, reliable, and California-specific source emission factors (EFs) for the natural gas industry. Screening values were measured by using portable monitoring instruments, and Hi-Flow samplers were then used to quantify fugitive emission rates. The component-level average EFs derived in this study are often smaller than the corresponding ones in the 1996 EPA/GRI study. The smaller EF values from this study might be partially attributable to the employment of the leak detection and repair program by most, if not all

Human capital for the future of the gas industry: Delivering on talent. Welcoming the youth

Popescu, Marius; Le Gourrierec, Meline

2015-01-01

The gas industry has clearly identified one issue: it must attract young professionals to replace the previous generations of working people. The natural gas sector expanded rapidly in the mid-nineteen sixties with the first large import-export contracts of Dutch and Russian gas, the in the mid-seventies with several other sources (Algeria and Norway). It is now a global industry. Today's objective is to develop activities along the entire gas chain, both upstream and downstream. Therefore, it is necessary to attract the best researchers, managers and technicians to meet the new challenges of this expanding industry. Currently, the gas workforce remains predominantly masculine. Increasing the number of women employees is also a necessity for the sector. This requires improving communication and attracting young women into taking up scientific and technical studies. Together with the World Gas Conference organised in Paris, the second edition of the Youth Event is being held. Interactivity, professional network, exchanges, talks...: 3,4 and 5 June are dedicated to the future of the gas sector

Full text: High emission of SO 2 and NO x in the process of fossil fuel combustion creates a major world environmental problem. Poland which uses for energy production mainly pit and brown coal produces these pollutants as well. The certain amount of SO 2 and slightly less NO x pollutants is introduced into the atmosphere. 1/2 of SO 2 and 1/3 NO x pollution is contributed by heat and electricity generating boilers. The biggest sources of pollution are located in south west side of Poland and are connected with industrial centers but over 45% of the total 802 and 69% of NO x pollutants distributed over polish territory come from external sources. The laboratory facility for flue gas treatment radiation technology was organized in Institute of Nuclear Chemistry and Technology at Warsaw at the end of 80s. Soon after the pilot plant for flue gas treatment with electron beam has been installed at Power Plant Kaweczyn near Warsaw. The flow capacity trough those installations was respectively 400 and 20000 Nm /h. Three new elements have been introduced to the construction of the radiation chamber in Polish pilot installation. Those are: cascade double stage irradiation, longitudinal irradiation, (beam scanned along the chamber axis) and the air blow under the chamber window with the purpose to create air curtain separating the window from the flue gases causing corrosion. Three different system for filtration aid has been constructed and tested: bag filter, gravel bead filter and electrostatic precipitator. The pilot plant installation was used to establish the optimal parameters of industrial facility: optimizing of the process parameters leading to reduction of energy with high efficiency of SO 2 and NO x removal; selecting and testing filter devices and filtration process; developing of the monitoring and control systems at industrial plant for flue gas cleaning, preparation of the design for industrial scale facility. The positive results of the tests performed on

GAS AND COAL EXTRACTIVE INDUSTRY DURING THE SOCIALIST INDUSTRIALIZATION PERIOD (1948-1989

2015-12-01

Full Text Available This article shows that since 1949 the extractive industry has undergone a strong process of restructuring when enterprises were nationalized and a strict control over all components of the economy was established. The new leadership of the country had the intention of developing the industrial sector as well, basically laying the foundations of the new Romanian economy where the industrial sector economy would bring considerable income. This program will lead to the development of the energy sector in Romania also, thus contributing to a great extent to the development and consolidation of coal and gas extraction. Despite of all the economic and social development achieved during the period 1950-1989, at the end of it, Romania ranked a marginal position in the European countries hierarchy since between its level of development and the market economy developed countries large gaps in respect to the main economic and social indicators occurred.

Water-gas shift. An examination of Pt promoted MgO and tetragonal and monoclinic ZrO2 by in situ drifts

In situ DRIFTS measurements on unpromoted and Pt promoted MgO and ZrO 2 (both tetragonal and monoclinic) indicate that at high H 2 O/CO ratios, where the reaction rate has been reported to be zero order in H 2 O and first order in CO, the mechanism involved in the catalysis of water-gas shift is likely a surface formate mechanism, in agreement with Shido and Iwasawa. Pt was found to catalyze the removal of surface carbonates and to facilitate the generation of active OH groups relative to the unpromoted catalyst. Comparison with Pt/ceria revealed that the OH groups involved in the catalysis of magnesia and zirconia may be those of the bridging variety which occur at defect sites. That is, water dissociated over vacancies to produce bridging OH groups, as observed by infrared spectroscopy. The existence of such an adsorbed species is implied in the zero reaction order for water, where kinetics suggests that the surface should be saturated by an adsorbed water species. The lower extent of vacancy formation for magnesia and zirconia-based materials in comparison with ceria could explain a lower surface population of active bridging OH groups. CO was used as a probe molecule of the reduced centers, as it reacts with bridging OH groups to generate surface formates, a proposed WGS intermediate, and the decomposition of which is proposed to be the rate-limiting step. The trends in formate intensity by CO adsorption and CO conversion in WGS catalytic testing both followed the order: Pt/ceria>Pt/m-zirconia>Pt/t-zirconia>Pt/magnesia. In all cases, a normal kinetic isotope effect was observed in switching from H 2 O to D 2 O, consistent with a link between the rate-limiting step and the decomposition of surface formates, as noted previously by Shido and Iwasawa for Rh/ceria, MgO, and ZnO

A geographical perspective on the natural gas supply industry in the United Kingdom

International Nuclear Information System (INIS)

Chapman, Keith

2004-11-01

Natural gas has, over the last 40 years, come to account for a substantial percentage of primary energy consumption (i.e. including inputs to electricity and heat generation) in the United Kingdom (UK). In 2002, this percentage (37.3) was exceeded in only two other European countries, the Netherlands (46.0) and Hungary (43.0) (International Energy Agency, 2003). Although oil has generally attracted greater attention than natural gas, the effects of the latter upon the energy economy of the UK have, in certain respects, been more profound. Most North Sea oil production is exported directly from the UK (69.4 per cent in 2003 (DTI, 2004)) and the balance has been processed within an oil refining system originally established to handle imported oil. By contrast, the availability of natural gas from the North Sea from the mid-1960s transformed the UK gas industry from a producer of secondary energy (i.e. town gas manufactured from coal and oil) to a distributor of primary energy. This transformation had a geographical dimension evident in the contrast between the essentially local distribution systems of the town gas industry and the national system created to deliver natural gas. The development of this system has been accompanied by very significant organisational changes as the gas industry became one of several network utilities transferred from public to private ownership in the UK since the 1980s. This paper reviews these events from a geographical perspective. It is divided into three main sections. The first describes the growth of the natural gas consumption in the UK. The second places this empirical material within a policy framework. The third relates spatial variations in the availability and cost of natural gas to patterns of economic development and welfare. The introduction of natural gas from the North Sea into the UK energy market has clearly had major consequences at the national scale. It rapidly displaced the town gas industry, superimposing a

Recent rapid increases in the demand for city gas in manufacturing industries and future developments

International Nuclear Information System (INIS)

Kusano, Shigero

1992-01-01

City gas companies in Japan are experiencing an expansion in demand for gas in all manufacturing industries. The reason for this is, first and foremost, external, in that the first and second oil crises and the recent Gulf War have placed the oil market in a state of flux. That is to say, supply and demand in the oil products market is unstable while the stability of city gas, which is the main raw material for LNG, is being highly appraised. Another external reason is related to a subject much in the news recently the world over - the environment. City gas is highly regarded for its minimum environmental impact. Domestic reasons for the expansion include the fact that with the increase in use of city gas in manufacturing industries, the end user is beginning to recognize the various special qualities that city gas possesses. The expansion is also due in part to the unrelenting efforts in sales by the gas producers themselves. This report focuses on the expansion in demand in city gas over the past ten years from the point of view of Tokyo Gas as a producer that has been party to the increased sales of city gas in manufacturing industries for over 10 years giving views on the reasons for the increase. Graphic reports of the actual situation of the industry at meetings such as these are rare and therefore although this is slightly different from the main theme, I would like to proceed with the debate in the hope that this will be beneficial in the expansion of future gas demand in countries all over the world

Linking Effective Project Management to Business Strategy in Oil and Gas Industry through Decision-making Processes

Science.gov (United States)

Adeleke, Adeyinka

The construction project in the oil and gas industry covers the entire spectrum of hydrocarbon production from the wellhead (upstream) to downstream facilities. In each of these establishments, the activities in a construction project include: consulting, studies, front-end engineering, detail engineering, procurement, program management, construction, installation, commissioning and start-up. Efficient management of each of the activities involved in construction projects is one of the driving forces for the successful completion of the project. Optimizing the crucial factors in project management during each phase of a project in an oil and gas industry can assist managers to maximize the use of available resources and drive the project to successful conclusions. One of these factors is the decision-making process in the construction project. Current research effort investigated the relationship between decision-making processes and business strategy in oil and gas industry using employee surveys. I recruited employees of different races, age group, genders, and years of experience in order understand their influence on the implementation of the decision-making process in oil and gas industry through a quantitative survey. Decision-making was assessed using five decision measures: (a) rational, (b) intuitive, (c) dependent, (d) avoidant, and (e) spontaneous. The findings indicated gender, age, years of work experience and job titles as primary variables with a negative relationship with decision-making approach for employees working in a major oil and gas industry. The study results revealed that the two most likely decision-making methods in oil and gas industry include: making a decision in a logical and systematic way and seek assistance from others when making a decision. Additionally, the two leading management approaches to decision-making in the oil and gas industry include: decision analysis is part of organization culture and management is committed to

Assessment of an atmospheric fluidized-bed coal-combustion gas-turbine cogeneration system for industrial application

Energy Technology Data Exchange (ETDEWEB)

Graves, R. L.; Holcomb, R. S.; Tallackson, J. R.

1979-10-01

This study was initiated to provide information on the future potential industrial market for a cogeneration system consisting of a fluidized-bed coal combustor coupled to a gas-turbine (Brayton cycle) power system that uses air as the working fluid. In assessing the potential applications for the system, the process heat energy consumption by industry is identified, with special detail included on the six most energy-intensive industries. The potential impact on the nation's oil and natural gas consumption that would result from wide-spread utilization of coal for process heat is also estimated. The fraction of industrial process heat that the system could feasibly satisfy from a thermodynamic viewpoint is estimated, and the performance (potential fuel efficiency and heat/power ratio) of the atmospheric fluidized-bed gas-turbine system is calculated. Also treated are several specific case studies of industries in which the system could be incorporated. Major parameters are specified, and flow sheets are derived for systems that would satisfy the heat and power requirements of the process or industry. The overall fuel utilization efficiency, thermal power rating, and potential number of installations are specified for these case studies. The findings of the study indicate that there is a sizable potential market for the system, with over 1000 possible installations disclosed after reviewing only 8 specific industries from 6 major Standard Industrial Classification (SIC) groups. The potential displacement of oil and gas by coal in process heating is shown to be about 1.60 m/sup 3//sec (870,000 bbl/d) of oil and 4590 m/sup 3//sec (14.0 billion ft/sup 3//d) of natural gas for all industries combined. Continued development of the fluidized-bed coal combustor and power system is recommended so that this potential may be at least partially realized.

Naturally occurring radioactive material in the oil and gas industry

International Nuclear Information System (INIS)

Steingraber, W.A.

1994-01-01

Naturally occurring radioactive material (NORM) has been found in the Earth's crust and soil, the water we drink, the food we eat, the air we breathe, and the tissues of every living organism. It is relatively easy to determine open-quotes concentrationsclose quotes, or specific activity levels, in the range of 1 part per trillion for radioactive materials. With radioactive elements so abundant and detection possible at such low levels, the presence of NORM in oil and gas operations shouldn't be surprising. In fact, this presence has been recognized since at least the 1930's, but the phenomenon received only minimal attention in the United States until the mid-1980's. At that time regulatory agencies in several oil- and gas-producing states began to focus on NORM in the exploration and production segment of the industry, expressing concern over potential health and safety implications. The most significant aspects of NORM in oil production operations include original source, transport media, composition/radionuclides present, measurement methods, health/safety issues, waste classification, and waste disposal. In addition, I will summarize industry-sponsored NORM data collection and analysis efforts being conducted to aid in development of sound policies and procedures to address environmental, health, and safety issues. Current activities by state and federal regulatory agencies relevant to NORM in the oil and gas industry will also be reviewed

2004-01-01

The members of the French gas association (AFG) are fully aware of the responsibility they have in the domain of sustainable development. For us, it is a global commitment which consists in improving the impact of their activities in their different social, society, economical and environmental aspects. The environmental aspect is of primary importance with the Kyoto protocol and the obligation for France to reduce its greenhouse gas emissions. In order to better understand the implications of an environmental approach in the gas industry sector, this paper presents the actions and projects developed by Gaz de France and Total companies for the rational use of energy, the development of renewable energy sources (geothermal, wind and solar energies, hydrogen and fuel cells) and the abatement of the impacts of their activities on the environment: development of high efficiency equipments and appliances, improvement of existing fuels, development of natural gas for vehicles, LPG fuels and bio-fuels, investment in projects of greenhouse effect abatement (carbon prototype stock), reduction of works impact on the environment, geologic sequestration of CO 2 , recycling of coal mine gas, optimum processing of industrial effluents and wastes (development of gas-fueled processes) etc..

Building the NGV [natural gas vehicle] industry into the 21st century

International Nuclear Information System (INIS)

Eaves, M.

1992-01-01

The status and potential of the natural gas vehicle (NGV) industry is reviewed. The current status of NGV technology is discussed, and a perspective on the business potential of NGV is offered. The cost of compressed natural gas is compared with the cost of conventional fuel options. At present there is a ca 92-97 cent/gallon differential between natural gas and gasoline, however it is not clear that this is sufficient to provide an incentive for purchasing a compressor. The economics of running a Sierra pickup truck are calculated, and it is proposed that a fuel cost differential in the order of 30 cents may be enough to entice consumers to purchase NGV. The gas industry is expected to finance the fuelling infrastructure for NGVs for the reasonable future. The investment must be made using a 25-40 cent per therm differential (or 30-50 cent/gallon equivalent) to finance compressor facilities. Extensive tables and graphs are presented that show the dependence of number of vehicles (and gas sales) on simple payback periods for compressor facilities. 4 figs., 19 tabs

The olive oil industry generates during the extraction process several solid wastes as olive tree leaves and prunings, exhausted pomace and olive pits. These renewable wastes could be used for power and heat applications. The aim of this paper is to compare the performance of two small-scale CHP systems: a gasification- gas turbine system and an EFGT (externally fired gas turbine system). For this reason, several parameters have been calculated: generated heat and power, electric and overall efficiencies, biomass consumption, exergy efficiency, optimum pressure ratio, etc. These systems provide 30 kW e and about 60kW th . Simulation results show that the electrical and overall efficiencies achieved in EFGT system (19.1% and 59.3%, respectively) are significantly higher than those obtained in the gasification plant (12.3% and 45.4%). The proposed CHP systems have been modeled using Cycle-Tempo ® software. -- Highlights: ► Comparison between externally fired gas turbine and gasifier-gas turbine system. ► Olive oil industry generates several solid wastes as olive tree leaves and prunings. ► Thermodynamic parameters have been calculated. ► Systems have been modeled using Cycle-Tempo ® software. ► Simulation results show electrical and overall efficiencies achieved in the systems.

Particle size dependence of CO tolerance of anode PtRu catalysts for polymer electrolyte fuel cells

Science.gov (United States)

Yamanaka, Toshiro; Takeguchi, Tatsuya; Wang, Guoxiong; Muhamad, Ernee Noryana; Ueda, Wataru

An anode catalyst for a polymer electrolyte fuel cell must be CO-tolerant, that is, it must have the function of hydrogen oxidation in the presence of CO, because hydrogen fuel gas generated by the steam reforming process of natural gas contains a small amount of CO. In the present study, PtRu/C catalysts were prepared with control of the degree of Pt-Ru alloying and the size of PtRu particles. This control has become possible by a new method of heat treatment at the final step in the preparation of catalysts. The CO tolerances of PtRu/C catalysts with the same degree of Pt-Ru alloying and with different average sizes of PtRu particles were thus compared. Polarization curves were obtained with pure H 2 and CO/H 2 (CO concentrations of 500-2040 ppm). It was found that the CO tolerance of highly dispersed PtRu/C (high dispersion (HD)) with small PtRu particles was much higher than that of poorly dispersed PtRu/C (low dispersion (LD)) with large metal particles. The CO tolerance of PtRu/C (HD) was higher than that of any commercial PtRu/C. The high CO tolerance of PtRu/C (HD) is thought to be due to efficient concerted functions of Pt, Ru, and their alloy.

Supersonic He and Ar atomic beam scattering from C{sub 60} and graphene monolayers adsorbed on a Pt(111) surface are demonstrated in order to obtain detailed insight into a gas-molecule collision that has not been studied in detail so far. The effective masses and phonon spectral densities of the monolayers seen by different projectiles are discussed based on classical models such as the hard cube model and the recently developed smooth surface model. Large effective masses are deduced for both the monolayers, suggesting collective effects of surface atoms in the single collision event. The effective Debye temperature of graphene was found to be similar to that reported in highly oriented pyrolytic graphite (HOPG), indicating that the graphene is decoupled well from the Pt substrate. A much smaller Debye-Waller factor was found for the C{sub 60} layer, probably reflecting the strong C{sub 60}-Pt(111) interaction.

Electricity in lieu of nautral gas and oil for industrial thermal energy: a preliminary survey

Energy Technology Data Exchange (ETDEWEB)

Tallackson, J. R.

1979-02-01

In 1974, industrial processors accounted for nearly 50% of the nation's natural gas consumption and nearly 20% of its consumption of petroleum. This report is a preliminary assessment of the potential capability of the process industries to substitute utility-generated electricity for these scarce fuels. It is tacitly assumed that virtually all public utilities will soon be relying on coal or nuclear fission for primary energy. It was concluded that the existing technology will permit substitution of electricity for approximately 75% of the natural gas and petroleum now being consumed by industrial processors, which is equivalent to an annual usage of 800 million barrels of oil and 9 trillion cubic feet of gas at 1974 levels. Process steam generation, used throughout industry and representing 40% of its energy usage, offers the best near-term potential for conversion to electricity. Electric boilers and energy costs for steam are briefly discussed. Electrically driven heat pumps are considered as a possible method to save additional low-grade energy. Electrical reheating at high temperatures in the primary metals sector will be an effective way to conserve gas and oil. A wholesale shift by industry to electricity to replace gas and oil will produce impacts on the public utilities and, perhaps, those of a more general socio-economic nature. The principal bar to large-scale electrical substitution is economics, not technology. 174 references.

Fugitive emission inventory from Brazilian oil and gas industry (2000-2005) and discussion of mitigation measures

2008-07-01

The objective of this work is to evaluate current emissions of GHGs within the Brazilian oil and gas industry, specifically the fugitive emissions arising from exploration and production. Besides, projects for mitigating these emissions and opportunities for the national industry are investigated. Results show that N{sub 2}O contributes little to fugitive emissions from the oil and gas industry, principally from gas sector. NMVOC emissions are significant, principally from the oil sector. In relation to CO{sub 2} and CH{sub 4} emissions, the oil sector emits more CO{sub 2} while the gas sector contributes more to CH{sub 4} emissions. In both sectors flaring is the activity that emits most CO{sub 2}. In relation to CH{sub 4} the principal contribution to emissions are from exploration and production onshore, although offshore activities as a whole play a greater part in the national industry. The results make it clear that the use of gas from flaring activity is a great opportunity for emission mitigation projects. From a business point of view, methane emissions could mean lost opportunities in selling natural gas. The Kyoto Protocol mechanisms, as the Clean Development Mechanism and Joint Implementation actions, provide the opportunity to stimulate investments in projects for reducing flaring and venting of associated gas.

2018-05-01

Quick and efficient detection of low concentrations of hydrogen remains a challenge because of the stability of hydrogen. A sensor based on reduced oxide graphene functionalized with Pt nanoparticles is successfully fabricated using a freeze-drying method followed by heat treatment. The structure and morphology of the Pt@rGO nanocomposites are well analyzed by X-ray diffraction, field emission scanning electron microscopy, transmission electron microscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy. The as-prepared Pt@rGO nanocomposites show excellent hydrogen gas sensing properties at a low working temperature of 50 °C. The sensitivity toward 0.5% hydrogen is 8%. The response and recovery times of the sensor exposed to 0.5% hydrogen are 63 and 104 s, respectively. The gas-sensing mechanism of Pt@rGO sensor is also discussed.

The production activity has high dependence on the usage of diesel, which influences the quality of the product and the cost of total business. The price fluctuation is one of the reasons for the company to convert the usage of diesel to some energy alternatives. Gas is the best alternative to replace diesel due to some advantages such as price, installation cost, distribution issue, calorie level, and environmental issue. There are some resistances from internal organization emerge in the implementation of the conversion. The alternatives strategy has been explored to reduce the resistances considering the goal of the organization, the actors (department in the company, and the type of resistance using analytical hierarchy process method. The priority strategy is establishing a new division for handling the conversion program and installing the gas facility gradually.

Nanostructured Pt-based alloys show great promise, not only for catalysis but also in medical and magnetic applications. To extend the properties of this class of materials, we have developed a means of synthesizing Pt and Pt-based alloy nanoclusters in the capsid of a virus. Pure Pt and Pt-alloy nanoclusters are formed through the chemical reduction of [PtCl 4 ] − by NaBH 4 with/without additional metal ions (Co or Fe). The opening and closing of the ion channels in the virus capsid were controlled by changing the pH and ionic strength of the solution. The size of the nanoclusters is limited to 18 nm by the internal diameter of the capsid. Their magnetic properties suggest potential applications in hyperthermia for the Co–Pt and Fe–Pt magnetic alloy nanoclusters. This study introduces a new way to fabricate size-restricted nanoclusters using virus capsid. (paper)

There have been reports of challenges in designing platinum carbon (Pt/C) electrode catalysts for PEMFC. Pt/C electrode catalysts deactivate much faster on the cathode (in moisturized O 2 ) than on the anode (in H 2 ). To understand influences of moisture and oxygen on the deactivation of the Pt/C catalysts in proton-exchange-membrane fuel cells (PEMFCs), spherical-aberration-corrected environmental transmission electron microscopy (AC-ETEM) was applied with a high-speed CCD camera. Structural changes of the Pt/C electrode catalysts were dynamically recorded in moisturized nitrogen, oxygen and hydrogen. The mass spectrometry confirmed the moisture content (between 5 to 30 %) of nitrogen driving gas through a humidifier. Coalescence of platinum nanoparticles (D = 3.24 nm) was carefully evaluated in pure N 2 and moisturized N 2 atmosphere. The Pt/C showed considerable structural weakness in a moisturized N2 atmosphere. Comparable results obtained by AC-ETEM in different gas atmospheres also suggested ways to improve the oxygen reduction reaction (ORR). In this paper, the deactivation process due to moisture (hydroxylation) of carbon supports is discussed using for comparison the movement of platinum nanoparticles measured in moisturized nitrogen and pure nitrogen atmospheres

The electrochemical characterization of two organic dyes (amaranth and procion orange MX-2R) has been performed on Pt electrodes and Pt electrodes coated with polyaniline and dispersed Pt. Electrodes with different Pt loads have been synthesized and characterized obtaining that a load of 300 {mu}g cm{sup -2} was the optimum one. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) was employed to observe the distribution and morphology of the Pt nanoparticles. The electroactivity of the electrodes has also been characterized by means of scanning electrochemical microscopy (SECM). The chemical characterization of Pt dispersed Pani coated Pt electrodes (Pt-Pani-Pt) was performed by means of X-ray photoelectron spectroscopy (XPS). The electrochemical characterization of the dyes has been performed by means of cyclic voltammetry. Voltammograms have shown that the presence of the dyes diminishes characteristic Pt oxidation and reduction peaks. However, redox processes due to the dyes, appeared in the voltammograms. The different species responsible of these redox processes were generated in the vicinity of the electrode and were not adsorbed on the electrode surface since after stirring, the different redox processes disappeared. Characterization with different scan rates showed that redox processes of both dyes were controlled by diffusion.

A first-principles study on the interaction of biogas with noble metal (Rh, Pt, Pd) decorated nitrogen doped graphene as a gas sensor: A DFT study

Density functional theory calculations are carried out to investigate the adsorption characteristics of methane (CH4), carbon dioxide (CO2), hydrogen (H2), hydrogen sulfide (H2S), nitrogen (N2), and oxygen (O2) on the surface of pyridine-like nitrogen doped graphene (PNG) as well as noble metal (Rh, Pt, Pd) decorated PNG to elaborate their potentials as gas sensors. The adsorption intensities of biogas on noble metal (Rh, Pt, Pd) decorated PNG are in the order of O2> H2S> N2> CH4> CO2> H2, which are corresponded to the order of their sensitivity on surface. Compared with biogas adsorption on pristine PNG, there exist higher adsorption ability, higher charge transfer and higher orbital hybridization upon adsorption on noble metal (Rh, Pt, Pd) decorated PNG. Consequently, the noble metal (Rh, Pt, Pd) decorated PNG can transform the existence of CH4, CO2, H2, H2S, N2, and O2 molecules into electrical signal and they could potentially be used as ideal sensors for detection of biogas in ambient situation.

In considering the potential of the United Kingdom for investment in the oil and gas industry, four factors are discussed. They are: the importance of certainty in identifying markets; the importance of infrastructure in assisting follow-on developments in mature oil and gas fields; the UK's competitive position in the world investment market; fiscal terms in the UK as compared with those offered by other countries. The conclusion drawn is that the UK needs to be responsive to its status as a mature oil and gas area and have the flexibility to stimulate investment in frontier areas. Stability in both the fiscal regime and also handling issues like market access is important. There is a need to capitalise on the many advantages conferred by the existing infrastructure in mature areas. (UK)

The role that government-industry cooperation has played in the development of the Canadian petroleum industry is recounted by way of providing background to delegates to the World Petroleum Congress taking place in June 2000 in Calgary, Alberta. Among individuals whose contributions have been vital to the development of the industry are the late Premier Manning of Alberta, and J. Howard Pew, President of Sun Corporation, Todd Montgomery, Michael Supple, Chris Hopkins, the triumvirate leaders of the privately owned SynEnCo Inc., the latest entry into the oilsands lineup, Dave Beckwerment and Jeff Arsenych, the visionaries behind Ravenwood Resources Inc., Robert McLeay, founder of Mera Petroleum Inc., and Robert Mansell, the economist who keeps tab on the industry from his home base at the University of Calgary. According to Mansell, four-fifths of Canadian oil and gas production is located in Alberta, which constitutes some 45 per cent of the country's economy. From manufacturing to communications and information technology, other sectors draw heavily on the oil and gas community for customers and talent. Despite occasional disparaging remarks applied to the industry as being 'a mature and sunset industry' it survives through its visionaries and adventurers who flourish in a cross-section of the community built by earlier pioneers, in various niches ranging from economical drilling for modest conventional reserves to international hunts for proverbial elephant-sized discoveries in world trouble spots. The staying power of the industry through upheavals of global proportions underlines the talent and policies that manage the Canadian petroleum industry, and provide an indication of the scale of the country's natural resources
